13 * @brief Fixed-size 5x7 bitmap font with ASCII and extended character support.
14 *
15 * Built on BitmapFont<5, 7, uint8_t, RGB_T> for glyph storage, pixel
16 * lookup, drawing, and text measurement - this class only adds its own
17 * built-in glyph table (the 95 printable ASCII characters) and a fallback
18 * lookup for codepoints outside that contiguous range (Latin-1/CP1252-ish
19 * accented/currency/symbol characters, mapped either to a purpose-built
20 * glyph or to the closest plain ASCII character), by overriding glyph().
