I use a regex, and apply it to the source and the indexed text.

it is pretty simple like:
preg_replace('/[àâäåãá]/iu','a',$x); preg_replace('/[éèêë]/iu','e',$x)

It is a bit of a hack, but works quite well in practice.  If you do some
googling, you can find many regex variations that will do what you want.
 Some get pretty involved such as handling ligatures (*ß -> ss)*
