from strcasecmp docs:

Binary safe case-insensitive string comparison. The comparison is not locale aware; only ASCII letters are compared in a case-insensitive way.

Contrary to the user id, there is no restriction on characters on login names.

Better to switch to mb_strtolower?

Oh yes I missed that (maybe because there is no mb_strcasecmp) so mb_strtolower is probably the best (better than Collator I think).
