Re: Case mapping of sharp s

[Juri Linkov <juri@jurta.org>]

BTW, does anyone know how to put a set of characters into one category
for the purpose of searching, without affecting case mapping?  I.e. to
not change the current case mappings, but allow a character from one
category to match all other characters from the same category.

`set-case-syntax-pair' is not suitable because it does this only for
a pair of characters and also changes case mappings.

Of course, it's possible to search with a regexp that matches
a character set in [...], or more convenient when a space in a regexp
is substituted with a set of characters from `search-spaces-regexp'.

I can't find a function like `set-case-syntax-pair' that would define
a set of equivalent characters for the search, so maybe this is not
possible.
