*
* @warning Though this is public in order to let the callback happen,
* calling it directly is not recommended.
* @note Based on Feyd's function at
* <http://forums.devnetwork.net/viewtopic.php?p=191404#191404>,
* which is in public domain.
* @note While we're going to do code point parsing anyway, a good
* optimization would be to refuse to translate code points that
* are non-SGML characters. However, this could lead to duplication.
* @note This function is heavily intimate with the inner workings of
* UTF-8 and would also be well suited in the Encoder class (or at
* least deferring some processing to it). This is also very
* similar to the unichr function in
* maintenance/generate-entity-file.php (although this is superior,
* due to its sanity checks).
* @param $matches PCRE matches array, with 0 the entire match, and
* either index 1, 2 or 3 set with a hex value, dec value,
* or string (respectively).
* @returns Replacement string.
