commit 565a89b2f4618249bd49349581b7eb8d85acd44a
Author: Thibaut Cuvelier <[email protected]>
Date: Wed Oct 30 20:12:54 2024 +0100
Parse the new list of Unicode characters.
I shamelessly copied the existing code for `symbols`, as it serves roughly
the same purpose. The new code might be hosted somewhere else if deemed
appropriate.
