A line of type in an Indic script (U+0900 to U+0DFF) is set again after it is read and compared with the glyphs the file drew: when it would draw other glyphs or put them elsewhere (a vowel sign the file draws before its consonant, a conjunct the file doesn't name), the line keeps the file's glyphs as outlines, with a note. Indic type in a font that isn't installed never draws as the file does, so it keeps the file's glyphs too; other type in such a font still shows in the fallback font (#4568). Tests: `crates/pdf/src/tests/reshaped.rs`. Scores unchanged. | | 2026-11-12 | minor | Save refusal follow-up (#6146): changed format opens its Save options; unchanged format retains original options. Focused UI regressions passed, including the format-change case that failed before the fix; native panel acceptance pending. Scores and estimates unchanged. | | 2026-11-11 | minor | Newly imported SVG/SVGZ titles use the imported-text rules: generated Untitled names and control-only titles give the filename fallback, other control characters are removed, and titles are limited to 65,536 characters. Native and Preserve Editing titles remain unchanged (#3626). | | 2026-11-11 | minor | Native and Preserve Editing restores keep an existing File Info title exactly, including repeated spaces; imported-text fallback titles alone are normalized (#3626). |
