This is wrong turn.

Exact the same can be said about text files: "environment locale 
settings could have no relevance for the byte sequence of the text. 
Moreover, it might be even invalid sequence in current locale, and then 
behaviour of sort would be undefined". Despite of this, we use 
localized sort in the system.

You made result of something like 'ls | sort' and alphasort() differs.

Please use strcoll() as POSIX said. It is user responsibility to set 
correct locale for non-suid programs, and for suid ones locale can't be 
set by user.
