Character Styles: Style Options sets Advanced Character Formats

Character Style Options and New Character Style get an Advanced
Character Formats section with Horizontal Scale, Vertical Scale,
Baseline Shift, Character Rotation and Language. Empty fields stay
unset, an explicit 100%, 0 degrees or English: USA stays distinct from
unset, and Reset Panel on the section clears only these five. Scales
take 1% to 10000% and baseline shift -1296 pt to 1296 pt, as
text.setRangeStyle does; rotation is stored from -180 to 180 degrees.
Language sets the language the characters are shaped in; hyphenation
and spelling do not change.

A field still as it opened keeps its stored value without the range
check, so a style captured from a scaled type object can be renamed.
The same applies to Basic's Size and Leading minimum.

charStyle.edit keeps a language tag that is not in the list when the
style already has it, so a style read from a file with such a tag can
be edited.

+Advanced Character Formats holds `h_scale` and `v_scale` (percent, 1 to 10000), `baseline_shift` (points,

 - **Character-style Auto leading:** capture and explicit style attributes retain Auto as a reset, distinct from omitted leading. Redefine and later numeric updates preserve local leading overrides; the Character Styles marker recognizes Auto correctly. Regression assertions cover partial definitions, Undo/Redo and native save/load serialization.

 - **Character Style Options, General and Basic Character Formats:** the dialog edits a style's name and stored character formats together. Empty fields remain unset, checkboxes show an indeterminate unset state, Basic's Reset Panel clears its explicit settings, and Preview can be canceled without changing history. OK saves one undo step; New Character Style offers the same fields from captured text or the interface language's defaults without a selection. Public reference: [Character and paragraph styles](https://helpx.adobe.com/illustrator/using/character-paragraph-styles.html).
+- **Character Style Options, Advanced Character Formats:** Character Style Options and New Character Style set a style's Horizontal Scale and Vertical Scale (1% to 10000%), Baseline Shift (-1296 pt to 1296 pt), Character Rotation and Language; text that uses the style takes them and keeps its local overrides. Empty fields remain unset, an explicit 100%, 0° or English: USA stays distinct from unset, and the section's Reset Panel clears only these five. Language sets the language the characters are shaped in, not hyphenation or spelling. Public reference: [Character and paragraph styles](https://helpx.adobe.com/illustrator/using/character-paragraph-styles.html) ("Adjust the Horizontal and Vertical Scale, Baseline Shift, Character Rotation, and Language options").
 - **Text styles redefined to the defaults:** New and Redefine Character Style and Paragraph Style capture every attribute of the selected text, including those at their defaults (Auto kerning, Roman baseline alignment, the default Hyphenation options, the Every-line Composer, no tab stops), and `charStyle.setAttrs` and `paraStyle.setAttrs` keep an attribute set to its default value. After a redefinition, text whose value still equals the old definition's takes the new value, a default included; local overrides stay, and text that still has the old value of an attribute the new definition leaves out goes back to the Normal style's value. The style panels show "+" only where the text differs from its style, including type with Auto alignment.
