Comment 4 for bug 518323

I am not familiar with python and unicode, but I know that in Drupal's Pathauto module this case is solved by manually created list of accented characters (and their replacements without accent). It seems like this:

; global transliteration
[default]
À = "A"
Á = "A"
 = "A"
à = "A"
Ä = "Ae"
Å = "A"
Æ = "A"
Ā = "A"
Ą = "A"
Ă = "A"
Ç = "C"
Ć = "C"
Č = "C"
Ĉ = "C"
Ċ = "C"
... etc.
