Summary

Reviewing https://github.com/matplotlib/matplotlib/pull/25359/files#diff-49ee499471e3397e95aa265c6694a643c8c16c625c700da06b9c3c58db69fc52 I noted that an annoying part is just looking at the codepoint values. One idea to improve readability would be to replace lines such as

(0x0393, 0x03a9, 'bfit', 0x1d71E), # \Gamma-\Omega

by

("\N{GREEK CAPITAL LETTER GAMMA}", "\N{GREEK CAPITAL LETTER OMEGA}", "bfit",
 "\N{MATHEMATICAL BOLD ITALIC CAPITAL GAMMA}"),

which seems much more self-documenting (and adapting the table reading code to support that seems easy enough and have negligible cost -- just a matter of calling ord() in a few places).

Proposed fix
