Your best option is probably GNU Recode (see the PHP manual and http://www.gnu.org/directory/recode.html) It will allow you to convert 8-bit characters to a 7-bit characters quickly and sanely: converting accented characters to their closest logical equivalent. Note: The method you chose is surprisingly speedy - it is a good 3-4 times faster than most other methods that are similar. However your fastest method for removing the offending characters would be to use preg_replace() - it should be about 4 times faster than the method you chose. --zak
