- Add CharTestScreen showing sample characters from 11 scripts (PL, DE, CS, FR, NO, HU, HR, TR, LT, Cyrillic, Greek) as raw UTF-8 to verify native font rendering without transliteration - Add "Char Test" entry to ToolsScreen menu - Regenerate LemonFont.h from lemon.bdf with full U+0020–U+04FF range: 1074 BDF glyphs + 174 placeholders, 4111 bitmap bytes; adds Greek (137 glyphs) and Cyrillic (256 glyphs) coverage; also fixes space advance (DWIDTH=5, was BBX+1=1) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
