The inconsistent behavior is very strange, and not something I've encountered before. However, here are a few notes:
1. Depending on your OJS configuration, characters may or may not be stored in the database in UTF-8 encodings. This means that MySQL will see the accented-E character as "Ãƒâ€°" but when it is actually used it will be correctly handled by OJS. See connection_charset and database_charset directives in config.inc.php for specifics.
2. If an error message or warning is being displayed at the top of the page, accented characters will not display properly.
If your installation of MySQL supports using utf-8 connection and storage (i.e. the directives in 1. can be set to utf8), you should have better results.
