Though to be fair, vim and Unicode both have their origins around 1987, so for one to know of the other would have taken a bit of miraculous prognostication. Despite existing since then, I don't recall hearing much about Unicode as a *common* standard until the early 2000s, so that's defensibly ~13 years of (semi-)obscurity during parallel development. The "ga" mnemonic of "[g]a=ascii value" made much more sense in the historical context. Now that Vim supports Unicode, "ga" shows the ordinal value depending on the internal encoding. If that internal encoding is UTF or UCS encoded Unicode (whether 8-bit, 16-bit, or 32-bit, big-or-little endian), then it shows the code-point. If it's a one- or two-byte encoding, vim returns that index. So the mnemonic should become "ga=ascii value or unicode code point along with possible combing/composing-character code-points". Not as helpful a mnemonic. As an aside, Vim also provides a "g8" command to show the decomposed hex bytes of a UTF-8 byte sequence if you want those values instead. Both should handle combining/composing characters as well. -tkc For more details within vim: :help ga :help g8 :help encoding-values -- https://mail.python.org/mailman/listinfo/python-list
