* feat(fonts): add dynamic font selection and font manager improvements - Add font-selector widget for dynamic font selection in plugin configs - Enhance /api/v3/fonts/catalog with filename, display_name, and type - Add /api/v3/fonts/preview endpoint for server-side font rendering - Add /api/v3/fonts/<family> DELETE endpoint with system font protection - Fix /api/v3/fonts/upload to actually save uploaded font files - Update font manager tab with dynamic dropdowns, server-side preview, and font deletion - Add new BDF fonts: 6x10, 6x12, 6x13, 7x13, 7x14, 8x13, 9x15, 9x18, 10x20 (with bold/oblique variants) - Add tom-thumb, helvR12, clR6x12, texgyre-27 fonts Plugin authors can use x-widget: "font-selector" in schemas to enable dynamic font selection that automatically shows all available fonts.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): improve error handling, catalog keys, and BDF preview - Add structured logging for cache invalidation failures instead of silent pass (FontUpload, FontDelete, FontCatalog contexts) - Use filename as unique catalog key to prevent collisions when multiple font files share the same family_name from metadata - Return explicit error for BDF font preview instead of showing misleading preview with default font Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): address nitpick issues in font management Frontend (fonts.html): - Remove unused escapeHtml function (dead code) - Add max-attempts guard (50 retries) to initialization loop - Add response.ok checks before JSON parsing in deleteFont, addFontOverride, deleteFontOverride, uploadSelectedFonts - Use is_system flag from API instead of hardcoded client-side list Backend (api_v3.py): - Move SYSTEM_FONTS to module-level frozenset for single source of truth - Add is_system flag to font catalog entries - Simplify delete_font system font check using frozenset lookup Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): align frontend upload validation with backend - Add .otf to accepted file extensions (HTML accept attribute, JS filter) - Update validation regex to allow hyphens (matching backend) - Preserve hyphens in auto-generated font family names - Update UI text to reflect all supported formats Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): fix lint errors and missing variable - Remove unused exception binding in set_cached except block - Define font_family_lower before case-insensitive fallback loop - Add response.ok check to font preview fetch (consistent with other handlers) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): address nitpick code quality issues - Add return type hints to get_font_preview and delete_font endpoints - Catch specific PIL exceptions (IOError/OSError) when loading fonts - Replace innerHTML with DOM APIs for trash icon (consistency) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(fonts): remove unused exception bindings in cache-clearing blocks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Chuck <chuck@example.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

The identity of the designer(s) of the original ASCII repertoire and
|
|
the later Latin-1 extension of the misc-fixed BDF fonts appears to
|
|
have been lost in history. (It is likely that many of these 7-bit
|
|
ASCII fonts were created in the early or mid 1980s as part of MIT's
|
|
Project Athena, or at its industrial partner, DEC.)
|
|
|
|
In 1997, Markus Kuhn at the University of Cambridge Computer
|
|
Laboratory initiated and headed a project to extend the misc-fixed BDF
|
|
fonts to as large a subset of Unicode/ISO 10646 as is feasible for
|
|
each of the available font sizes, as part of a wider effort to
|
|
encourage users of POSIX systems to migrate from ISO 8859 to UTF-8.
|
|
|
|
Robert Brady <rwb197@ecs.soton.ac.uk> and Birger Langkjer
|
|
<birger.langkjer@image.dk> contributed thousands of glyphs and made
|
|
very substantial contributions and improvements on almost all fonts.
|
|
Constantine Stathopoulos <cstath@irismedia.gr> contributed all the
|
|
Greek characters. Markus Kuhn <http://www.cl.cam.ac.uk/~mgk25/> did
|
|
most 6x13 glyphs and the italic fonts and provided many more glyphs,
|
|
coordination, and quality assurance for the other fonts. Mark Leisher
|
|
<mleisher@crl.nmsu.edu> contributed to 6x13 Armenian, Georgian, the
|
|
first version of Latin Extended Block A and some Cyrillic. Serge V.
|
|
Vakulenko <vak@crox.net.kiae.su> donated the original Cyrillic glyphs
|
|
from his 6x13 ISO 8859-5 font. Nozomi Ytow <nozomi@biol.tsukuba.ac.jp>
|
|
contributed 6x13 halfwidth Katakana. Henning Brunzel
|
|
<hbrunzel@meta-systems.de> contributed glyphs to 10x20.bdf. Theppitak
|
|
Karoonboonyanan <thep@linux.thai.net> contributed Thai for 7x13,
|
|
7x13B, 7x13O, 7x14, 7x14B, 8x13, 8x13B, 8x13O, 9x15, 9x15B, and 10x20.
|
|
Karl Koehler <koehler@or.uni-bonn.de> contributed Arabic to 9x15,
|
|
9x15B, and 10x20 and Roozbeh Pournader <roozbeh@sharif.ac.ir> and
|
|
Behdad Esfahbod revised and extended Arabic in 10x20. Raphael Finkel
|
|
<raphael@cs.uky.edu> revised Hebrew/Yiddish in 10x20. Jungshik Shin
|
|
<jshin@pantheon.yale.edu> prepared 18x18ko.bdf. Won-kyu Park
|
|
<wkpark@chem.skku.ac.kr> prepared the Hangul glyphs used in 12x13ja.
|
|
Janne V. Kujala <jvk@iki.fi> contributed 4x6. Daniel Yacob
|
|
<perl@geez.org> revised some Ethiopic glyphs. Ted Zlatanov
|
|
<tzz@lifelogs.com> did some 7x14. Mikael Öhman <micketeer@gmail.com>
|
|
worked on 6x12.
