Yes, yes, but — if you will allow me to return to Lua and UTF-8 — there would
be more gain for a programmer if we had (if it is not too late already
for Lua 5.4)
utf8 versions of find, sub, match, gsub, gmatch, reverse. Just those, not asking
for upper/lower, operating only on simple codepoints, no combining characters,
no need for a C library.
utf8.find ("Hélène",'n') --> 5 5
utf8.sub ("Hélène",5) --> 'ne'
utf8.gsub ("Hélène","[éè]","e") --> 'Helene' 2
utf8.reverse ("Hélène") --> 'enèléH'
