I don't know if that has been requested yet. But here it is:
It seems that when a MySQL server is set with the UTF-8 connections (with the "SET NAMES utf8" SQL command) that, even if all the anope database is set to utf8_bin, it has trouble with accentuated characters. Data containing one of those chars will simply stop displaying.
So my suggestion request is that Anope MySQL supports utf-8 connections better. That way, data can ben entered into the database by anope correctly, and not halted when it hits an accentuated chars.
Thanks.
