I always thought these names were standardised within the Unicode standard, for example:

"LATIN CAPITAL LETTER U WITH OGONEK” for Ų

The rest being a matter of porting these names to symbols, but it’s just replacing spaces with underscores in a CL character literal:

#\LATIN_CAPITAL_LETTER_U_WITH_OGONEK

[a]

PS. both characters work in sbcl, but neither in LispWorks, which I might be running a limited version in my OpusModus environment, though

Hello parenthetical crowd

Is there a consensus about how to "name" Unicode characters, or every implementation does whatever it likes (thus breaking otherwise perfectly portable code)?

Cf., #\INFINITY

All the best

PS Do not even think to use the "hey, it is an implementation-dependent thing" argument!
