Emacs's search capabilities are language-agnostic.  So the number of
languages, whether finite or infinite, doesn't affect the issues being

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 and
script simply adds more assigned codepoints for its characters, but
has no effect whatsoever on character folding or on Emacs search

Are you saying that searching for א should not find ℵ?  Or that
looking for π should not find ℼ?  Or 1 shouldn't find 𝟏?  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 not
to do that.

> Char-folding is an indo-european centric sledge-hammer: heavy and limited.

This is nothing but unfounded name-calling.  Please don't.
