I know this is an old topic, but I wanted to add some thoughts on codepage 1252 [or other pages or unicode) and removing accented characters. The samples below should help with most European languages. Removing accents is a very 'English' thing to want to do, and the resulting names will make less sense to other nationalities! However if you have a large music collection, inconsistently tagged over time, it's much easier afterwards to find all references to an artist.
I'm copy/pasting from a spreadsheet so I can't be sure the text will look correct or not, and you should try copy/pasting from this page back into your package of choice. Although created in WIndows language=En-UK, I think this will work for many of you. I Can't guarantee the code will make sense after posting - I'll check and the post a file if need be.
If you copy multi-line please remove breaks to make one line of text for each command.
For example:
$replace(%album%,À,A,Á,A,Â,A,Ã,A,Ä,A,Å,A,à,a,á,a,â,a,ã,a,ä,a,å,a,Æ,AE,æ,ae,Ç,C,ç
