With collation also possible with XS/C, but with a different result than
in perl, I think that there should be a way to use perl unicode
collation from C too, in addition to using a unicode collation or not.

Should it be a separate customization variable, or should
USE_UNICODE_COLLATION be replaced by a variable with a textual value
taking more possibilities, for example USE_COLLATION with possible
values:
unicode
unicodeperl
basic

?
