Think also at ancient langu= ages. Emacs's search capabilities are language-agnostic. So the number of languages, whether finite or infinite, doesn't affect the issues bein= g discussed. Generally, with very few exceptions, letters and symbols that belong to some script are not folded to or with characters of other scripts, because the Unicode database precludes that. So each new language an= d script simply adds more assigned codepoints for its characters, but has no effect whatsoever on character folding or on Emacs search capabilities. > Think at math and new symbolic languages. Are you saying that searching for =D7=90 should not find =E2=84=B5? = Or that looking for =CF=80 should not find =E2=84=BC? Or 1 shouldn't find = =F0=9D=9F=8F? Not even as an option? Why should we deprive Emacs users of such an important feature? Those who don't want it can always customize their Emacs no= t to do that. > Char-folding is an indo-european centric sledge-hammer: heavy and l= imited. This is nothing but unfounded name-calling. Please don't.
