A paragraph that ends in a soft return ends with the empty line after it,
so the line the soft return ends is justified like any other; it was taken
for the paragraph's last line and left aligned.
In right-aligned area type, the text before a line's last tab sits at its
stops, measured from the left edge, and the text after it (none when the
tab ends the line) against the right edge. The line was laid out from the
left and aligned as a whole, which moved its start off the left edge and
its tabs' text off their stops. Illustrator's own layout in a user's .ai
sets its price lists so. Centred and justified lines are aligned as a
whole as before.
- Auto leading stays auto: each line takes the paragraph's share (key 7)
of the largest type on it. The leading was the first two lines'
distance for every line, so 10 pt lines under a 15 pt heading came in
18 pt apart.
- The paragraph's hyphenation options (keys 10 to 15) are read.
- Area type of one frame whose last lines the file sets, but which don't
fit here (the fallback font, or a descent past the frame's bottom),
gets a frame taller from its bottom (vectorcraft_text::fit_source_lines),
with a warning.
A user's .ai whose type differed from its page by 6.6%, so that it opened
from its PDF part with each line its own text object, now opens from its
layers.
In Justify Left, Center or Right, only the paragraph's last line keeps its
alignment; a line that a soft return (U+2028) ends is spread to the frame's
edges like any wrapped line. Illustrator's own layout in a user's .ai sets
such lines justified, and VectorCraft left them ragged.
Features take a value (tag=N) in style commands, SVG and native files. Runs that
differ only in their feature lists are shaped in one buffer with ranged features, so
an alternate on one letter of an Arabic word keeps the word joined. FontFace reads
GSUB once (alternate sets, singles, the feature reaching a glyph), names unencoded
glyphs, and alternates_in_context finds a character's alternates in its word.
text.setRangeStyle takes glyphAlternate: null.
A new test binary opens a document of 13 type objects with the plans a
font face keeps and again while every shaped segment makes its own plan.
The document, its cached bounds and baselines included, and the first
frame's pixels must be the same. `test_fonts::keep_shape_plans` switches
the plans off; it exists only in tests and with the `test-fonts` feature.
The engine's open test now builds objects of one script and direction
that differ in kerning and language, and lays each one out in a font
database of its own, so a plan used for the wrong features fails its
comparison. It no longer sets Arabic, which could fall back to a system
font in one database and not the other.
Every shaped segment built its own harfrust shaping plan, although a
plan depends only on the face, direction, script, language and features.
Opening a document lays out each type object once, so a document of many
short objects built thousands of identical plans.
A font face now keeps up to 32 plans, oldest dropped first, and shapes
with the one that matches. Feature ranges still come from the shape
call, so text with the same features over other ranges shares a plan.
The glyphs, bounds and baselines do not change.

Bulgarian was not among the text languages, so Bulgarian text could not
be tagged and fonts drew their Russian-style Cyrillic. Bulgarian (bg)
is now in the language list (Character panel, character styles,
text.setFormat by name or tag, the Hyphenation preference's default
language), with CLDR's quotes, „…“ at either level. Shaped as bg, the
fonts' locl forms for BGR apply: in the bundled Source Sans 3 Italic,
в, д, ж, з, к, л and ю take their Bulgarian forms.
Fixes#5945
Past a gutter of 1e300 a step no longer moves the baseline, so every cell of
a 100 x 100 frame was searched for all MAX_STEPS steps: over 40 s per layout.
AreaOptions::gutter has no limit, so a saved file can do this.

When a frame's text ends with a paragraph break and the next frame is empty, restyling that empty frame was undone on reflow: an unedited empty frame after it gave the story's last paragraph its own style again. A restyled empty frame now keeps its style against unedited empty frames that follow it. Unedited empty frames before it, later frames with text and later restyled frames still give the paragraph their style, as before.
To find the characters that justification or Mojikumi moves, SVG export
without Fewer <tspan> Elements laid out every live type object a second
time, as point type with
Mojikumi None and default Justification options, whenever its paragraph
had Mojikumi on. New type gets Line-end Punctuation Half Width, so every
new type object was laid out twice. Mojikumi only spaces Japanese
punctuation and Japanese letters, so type without them lays out the same
either way.
- TextLayout::mojikumi_applies says whether the text or a list marker
holds a character Mojikumi spaces.
- reader_advances keeps such a paragraph's Mojikumi, and reads the glyphs
from the layout it was given when the object it would lay out is the
same; otherwise it lays the object out again as before.
The SVG is unchanged. Exporting 5,000 point type objects takes a median
of 109.4 ms instead of 171.5 ms on Windows 11.
Ka, the halant, Ka again and the vowel sign I are shaped as one cluster:
the vowel sign, the first Ka's half form, then the second Ka's default
glyph. The glyph lookup looked for the character's default glyph across
the whole cluster before its alternates, so for the first Ka it found
the second Ka's default glyph instead of the half form. It again goes
through the cluster in order, and takes the first glyph that is the
character's default glyph or one of its alternates and is not the
default glyph of another character of the grapheme, so a vowel sign's
glyph that the font also lists as an alternate of the consonant is not
reported for the consonant.
text.glyphAlternates reported the default glyph as `chosen` for any
character that overflows its area. A character whose style substitutes
another glyph (`salt`, or `vert` in vertical type) was reported with a
glyph it is not drawn with. The query now shapes such a character alone,
with the rest of its grapheme in their own styles and in the text's
writing direction, by the same helper text.setGlyphAlternate uses.
The helper also shapes the character in the direction its paragraph
sets it in, from its bidi level, so a parenthesis set right to left is
reported with its mirrored glyph in both commands.
A document font drawn in a substitute style stayed listed and could be chosen as the
replacement: the family is installed, so the old check passed, and Change sent the
unavailable style to text.replaceFont, which stored it and warned that the text is drawn
in a stand-in. The exact face now decides both the automatic choice and whether Change
is available; the row stays listed.
Listing System asked the font database for each family's style-less face, and for a
family not loaded yet that reads all its cataloged files, so opening the dialog could
load a whole font library. FontDb::closest_style answers from the catalog's weight and
slant instead, and the rows put that style first as before.
Tests: the dialog's 26 (the closest style is the face a style-less request resolves to,
a stand-in style is listed but not chosen) and the text crate's 474.
text.glyphAlternates reported the first glyph of the character's
cluster as the chosen glyph. A vowel sign drawn before its consonant
(Devanagari Ka with the vowel sign I) comes first in that cluster, so
the query reported the vowel sign's glyph for Ka, while
text.setGlyphAlternate reported Ka's own glyph. Both commands now take
the character's glyph by the same rule, and so does the check in
text.setGlyphAlternate that the chosen glyph is drawn.
A character that overflows its area is shaped with its grapheme, and
each character of the grapheme now keeps its own style there, so a
nukta of another size no longer makes a ligature with its consonant
that the laid-out text does not draw. A test font with a Devanagari
nukta ligature checks both.
Optical moved every pair all the way to a fixed 0.08 em ink gap, tighter
than most text faces' own stem spacing, so ordinary text was squeezed
(at 100 pt, Source Sans 3 `nn` closed from 54.7 to 46.9 pt).
Each pair now moves 0.6 of the way toward the face's reference gap (the
median ink gap of `nn`, else `HH` or `oo`; 0.08 em when it has none),
keeps at least 0.3 of it at its narrowest, and changes by at most
0.12 em tighter or 0.06 em looser. Ideographs, kana, hangul, fullwidth
and CJK punctuation forms and dashes keep the font's spacing.

Follows #5442.
- text.setGlyphAlternate keeps the default glyph as a choice when a
feature of the character's style (salt, a stylistic set) draws another
glyph for it, so the default glyph is drawn. A character that is not
laid out (overflowing text) is shaped alone in its style to decide.
gid: null reports the glyph the style draws.
- The Glyphs panel's alternates grid shows the default glyph first when
the font does not list it, so a chosen alternate can be put back.
- A test for a chosen character that starts a longer grapheme (f with a
combining acute), which is not split from its mark.
- The alternates tests in the engine hold the shared font lock while
they add fonts to the global font database.
With System Layout on or Fractional Widths off, each advance is rounded
to whole points, but a right-to-left character with manual kerning
still moved by the unrounded kerning value. The difference between the
two changed the space after the character before it in reading order.
The character now moves by the change the kerning makes to its rounded
advance, so only the space before the next character changes.
Baseline shift on an upright glyph in vertical type moved it up the column
instead of across it, at any Character Rotation, because the shift was
applied before the glyph was turned upright. The shift is now taken off
before the turn and put back after it, so an upright glyph moves across the
column by the shift as a letter lying on its side does, and still turns
about its shifted pen position.
The menu bar builds Type > Font in every frame, the first included, and
its family list waited for the scan of every installed font. When that
scan took longer than the 20 s first-frame watchdog (thousands of fonts
on a slow disk, or each file checked by antivirus), the app took the
graphics adapter for hung and started again without it, until none was
left and no window ever showed.
The menu now lists the fonts already loaded until the scan ends, then
all of them (FontDb::menu_family_list_now, installed_fonts_ready).
optical_pair_after_rtl_separate_mark_uses_base_outline sets Noto Sans
Arabic, which is not in assets/fonts. Without CRAFT_FONTS_DIR the font
database returns a fallback face, so the test checked that face instead.
The test now skips when Noto Sans Arabic is missing, as the Shippori
Mincho tests in the same file do.
A variable font can leave an ssNN feature empty in GSUB or GPOS and
supply its lookups through a FeatureVariations substitution. The
OpenType panel skipped those sets because the default feature has no
lookups. A set is now listed when a substitution in a variation record
replaces its feature with one that has lookups, and its name is read
from the default feature or the substituted one.
Records after one without conditions are ignored, and at most 4096
variation records and 4096 substitutions are read per table.
Follows #5447.
StylisticSet.name now holds only a name the font supplies. The OpenType panel shows a set without one as `Set {n}` through tl!, so the label is translated, and each UI catalog has a `Set {n}` row.
With SCALED_COMPONENT_OFFSET, a component's offset now scales each axis
by the length of that axis's basis vector, as the outline loader does,
instead of going through the whole matrix. A rotated or skewed
component's caret no longer lands away from its drawn point.
UNSCALED_COMPONENT_OFFSET now turns the scaling off when both flags are
set.
A composite glyph whose components expand into glyphs with no points
could make the contour-point caret lookup read billions of glyphs. The
whole lookup now shares a budget of 65,536 glyph reads and gives no
caret when it runs out, so the caret falls back to dividing the advance.
On a path, vertical type turns an upright glyph about its pen, so its cell
runs from 0.12 em before the pen to 0.88 em after it without the font's
vertical metrics. The ligature caret, a click and the selection measured
the cell from the pen instead. They now take the cell where the glyph's
transform draws it, with its placement, baseline shift, Horizontal Scale
and Skew.
A manual kerning value on an inline graphic's character was stored and
shown but did not move the text after it. The graphic's advance now
includes the value, as a letter's does, and in right-to-left horizontal
type its art moves right by the value, so the space goes between it and
the next character in reading order. Auto and Optical kerning still apply
no font pairs to an inline graphic.
Right-to-left manual kerning was added to the glyph's offset, which
Character Rotation turns, so a rotated character with kerning moved
across the line (up at 90 degrees) instead of away from the next
character in reading order. The shift is now applied to the pen
position along the baseline, outside the rotation, and the rotation
turns the glyph about that moved pen position.
A manual kerning value on a character in right-to-left text changed the
space between it and the character before it in reading order, under
both Auto and Optical kerning. The shaped glyphs of a right-to-left
cluster now also move right by the value, so the space its advance
gains is at its left, between it and the next character in reading
order. Left-to-right text and tracking are unchanged.
Optical kerning no longer takes the left glyph's manual value off the
advance it measures, since right to left the value is in that glyph's
offset as well.
