Subject: [tip/offtopic] A function to describe the characters of a word at point
Date: Wed, 13 Jul 2022 10:49:48 +0000 [thread overview]
Message-ID: <87y1wxwalv.fsf@posteo.net> (raw)
Sorry for the slight offtopic.
Since Unicode and character issues come up here from time to time, I'm
sharing this 'homemade' function that I wrote a long time ago for my
work, in case someone finds it useful. It Shows a brief descriptive list
of all characters in a word at point. Each character includes the
Unicode name, code, and canonical decomposition. Example:
ἄρχοντα >>
ἄ (#1f04) ... GREEK SMALL LETTER ALPHA WITH PSILI AND OXIA ... descomp: #1f00 #301
ρ (#3c1) ... GREEK SMALL LETTER RHO ... descomp: #3c1
χ (#3c7) ... GREEK SMALL LETTER CHI ... descomp: #3c7
ο (#3bf) ... GREEK SMALL LETTER OMICRON ... descomp: #3bf
ν (#3bd) ... GREEK SMALL LETTER NU ... descomp: #3bd
τ (#3c4) ... GREEK SMALL LETTER TAU ... descomp: #3c4
α (#3b1) ... GREEK SMALL LETTER ALPHA ... descomp: #3b1
