This is a bit worrying, since the given case is one of the most important ones -- UtfNormal::cleanUp() is supposed to normalize combining characters, and here it's not tripping correctly.
Not quite sure why this is failing, needs investigation.
The recent commit w/ iconv support doesn't seem to be tripping the issue for me. Tested so far w/ PHP 5.2 & 5.3 custom-built on Mac OS X 10.6.
