  • My focus: European Medieval handwritjng
  • Pre-Gutenberg

–

Handwritjng

–

Early print → imitatjng handwritjng

  • Alphabetjc writjng systems

–

Latjn script (Italian, English...), Greek, Cyrillic...

–

No Cuneiform, Arabic, Chinese etc.

Unicode: the short way out (as TEI says)?

  • Solutjon for new digital texts
  • Not enough for pre-modern writjng systems

–

Ligatures

  • & (U+0026; ASCII 38)
  • Have I encoded that it is equivalent to “e + t” in that MS?

–

Allographs

  • ſ (U+017F) / s (U+0073; ASCII 115)
  • Have I encoded that they are variants of grapheme <s>?

–

Grapheme set

  • u (U+0075; ASCII 117)
  • Have I encoded whether it “covers” (or not) <u> and <v>?
