unicode_age

A package for determining what version a Unicode codepoint was added to the standard

This package's version X.Y.Z.U tracks Unicode version X.Y.Z, with U reserved as a release counter for updates unrelated to the Unicode version.

Example usage

>>> import unicode_age
>>> codept = ord("\N{SNAKE}")  # added in Unicode 6.0
>>> print(unicode_age.version(codept))
(6, 0)

Rationale

Before writing this module, I was parsing DerivedAge.txt into a list[int | None], but this approach consumes an atrocious amount of memory (10 MB) for what it is. Using the representation here consumes three orders of magnitude less memory (~30 KB), and it was kinda fun to write besides :)

Updating

The script makeunicode_age.py consumes DerivedAge.txt and produces the unicode_age_db.py file that holds the backing data for this library. To make a build for another version of the Unicode Character Database, you should be able to replace DerivedAge.txt with the latest version and re-run this script.
