I'm having a weird problem with using WP own tagcloud. It seems that alphabetic sorting is not suported for languages that are using non-English characters.
For example: Our language is using a "č" (c with scaron) which is positioned beetwen "c" & "d" in alphabet. But wp_tag_cloud() function bring tags with "č" at the start, before "a" words. Same goes for "š"(s with scaron) and "ž" (z with scaron).
the_tags() instead works perfectly. It sorts the tags in right alphabetic order.
It seems that wp_tag_cloud() is not considering "international" characters as the_tags().
Is there anyone that solved this?
