Why 8859 is special

Latin-1 is part 1, and the family's problem is that a document does not record which part it uses — so the same bytes render as different languages depending on an assumption. Unicode exists to end that guessing.

2 × 4,096 + 1 × 512 + 2 × 64 + 3 × 8 + 3 × 1 = 8,859

Hexadecimal

2 2 9 b

2 × 4,096 + 2 × 256 + 9 × 16 + b × 1 = 8,859

Read as powers of two: 8,192 + 512 + 128 + 16 + 8 + 2 + 1 = 8,859.

In historical numeral systems

Egyptian

8 lotuses, 8 coils of rope, 5 hobbles, 9 strokes

8 × 1,000 + 8 × 100 + 5 × 10 + 9 × 1 = 8,859. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

UTF-8 is self-describing where ISO 8859 is not, which is why a UTF-8 file cannot be mistaken for a different language's encoding.

Technology & computing

  • ISO 8859 has sixteen parts, and a file gives no indication which one it was written in. Text that renders correctly in one part is nonsense in another, which is the specific problem Unicode was created to remove.
