Hi!
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.
