[dokuwiki] Re: Performance issues

The utf8_substr function in Harry's phputf8 (contributions by Andreas Gohr, et al) library is also much more efficient than the current dokuwiki function.

 phputf8 : 0.08seconds

The utf8_substr function can be used as a drop in replacement for the current one and the logic to use mb_substr() can be added. Or maybe it'd be worthwhile completely replacing/substituting the current dokuwiki utf8.php for phputf8. With the full thing the mb_string library check is done once and appropriate functions included.
