The only solution I come to is to set a bunch of If and review each and every non ASCII vowels to remplace it by its ASCII counterpart
If Key = "É" Or Key = "È" Or Key = "Ë" Or Key = "Ê" Then
key = "E"
Same apply for AEIOUY characters
I actually strips these characters (in fact I only keep a-z characters), but I used one of these characters and without it the word looks jazzy) and that looks as amateur in the worst meaning.
Is there’s anothe way to achieve that goal ?
