The misc-fixed font (full Latin/Greek/Cyrillic) had only ever reached SH1106Display and the e-ink driver. GAT562 30S -- like 24 other variants -- uses SSD1306Display, which stayed on the built-in 5x7 font, so every keyboard alphabet beyond ASCII and every accented contact name was transliterated (Łódź -> Lodz) or drawn as a filled block. Extract the renderer into MiscFixedRenderer.h rather than copying it: Adafruit_SH110X and Adafruit_SSD1306 both derive from Adafruit_GFX and glyph drawing is pure pixel plotting, so one implementation serves both drivers (-79 lines from SH1106Display.cpp, same flash usage as before). The header is .cpp-only by contract -- the font tables are static const, so including it from a driver header would land a copy in every translation unit. On SSD1306 the path is opt-in behind OLED_MISC_FIXED_FONT, set only in the two GAT562 30S solo envs: the font costs ~14 KB of flash and the other 24 variants' repeater/companion builds have no keyboard to type those alphabets on. Without the flag that driver is unchanged, verified by building GAT562_30S_Mesh_Kit_repeater. Drive-by consistency fix from the extraction: a newline in print() now advances the cursor by yAdvance * text_size instead of a single yAdvance, which was half a row short at setTextSize(2). The e-ink driver always scaled it. No effect at size 1, which is everywhere the UI prints '\n'. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
