/* IBM PC VGA BIOS font (codepage 437), used only for the hex-dump's ASCII column -
   a plain monospace font like JetBrains Mono has no glyphs for CP437's box-drawing/
   line/shade/symbol range, so every non-printable or extended (0x80+) byte in that
   column has to fall back to a generic placeholder. This one actually has them, so
   asciiChar() (index.html) can map every byte 0-255 to a distinct, correct glyph.
