In The Unicode Standard, Old Italic implementation is discussed in  Chapter 8 Europe-II: Ancient and Other Scripts. Language-specific fonts are required for processing text, as some of the common glyphs may differ slightly from language to language.

Old Italic was encoded in The Unicode Standard version 3.1. The script is encoded in the following block:
