1605 <b>WARNING:</b> If you use <b>backwards-compatible UTF-8</b> on MySQL 4.1+, and subsequently back up the database with <tt>mysqldump</tt>, it may destroy all non-ASCII characters, irreversibly corrupting your backups!.
1606 <br/><br/>
1607 In <b>binary mode</b>, MediaWiki stores UTF-8 text to the database in binary fields. This is more efficient than MySQL's UTF-8 mode, and allows you to use the full range of Unicode characters. In <b>UTF-8 mode</b>, MySQL will know what character set your data is in, and can present and convert it appropriately, but it won't let you store characters above the <a target="_blank" href="http://en.wikipedia.org/wiki/Mapping_of_Unicode_character_planes">Basic Multilingual Plane</a>.
