remove_accents is a hog

[skeltoac]

Profiling a page load with 61 remove_accents calls (sanitize_title does this) found that remove_accents was taking 86ms, or >1ms per call.

I added this to remove_accents as a first line:

if ( !preg_match('/[\x80-\xff]/', $string) ) return $string;

This reduced the total execution time to 1.8ms, or 0.03ms per call. Nice savings.
