Detailed Description

8x16 monochrome bitmap font, ASCII 0x20..0x7E.

Public-domain IBM PC VGA character set (code page 437), restricted to printable ASCII. The full 256-glyph BIOS font is documented in many places; the canonical archive used as the source for these bitmaps is:

VileR, "The Ultimate Oldschool PC Font Pack", https://int10h.org/oldschool-pc-fonts/ (Archive states: "All the original IBM-made fonts can be considered to be in the public domain.")

Each glyph is 8 pixels wide, 16 pixels tall, stored as 16 bytes with one byte per row, MSB on the left.

Public descriptor pointing at s_font_8x16_glyphs.

Public-domain glyph bitmaps reproduced from the IBM BIOS codepage 437 font, restricted to printable ASCII to keep the static footprint minimal (95 * 16 = 1520 bytes).
