Parameter expansion not working for all strings...
I'm trying to write a script that parses my music collection and hard link some filenames that my media player doesn't like to other names.

To do this I need to extract the name and remove alla non ASCII characters from that and do a cp -l with the result.

Problem is this:

Code:
22:16:58 $ find . -wholename "*" -print
./Simon & Garfunkel - The Essential Simon & Garfunkel (2003)/CD1/15 - Simon & Garfunkel - The Dangling Conversation (Album Version).flac
./José González - In Our Nature/06 Abram.flac
./Ane Brun (2004) - A Temporary Dive [FLAC]/09 Ane Brun - Song No. 6.flac

Code:
22:18:28 $ find . -wholename "*" -print| while read line; do echo ${line//[^a-z]/};done
SimonGarfunkelTheEssentialSimonGarfunkelCDSimonGarfunkelTheDanglingConversationAlbumVersionflac
./José González - In Our Nature/06 Abram.flac
AneBrunATemporaryDiveFLACAneBrunSongNoflac

Off cause I realize that those names are gibberish but what puzzels me is why the "./José González - In Our Nature/06 Abram.flac" line is unaffected.


Code:
22:21:12 $ bash --version
bash --version

My guess is that it has something to do with é but I wouldn't know.

Any ideas what could be the problem?

Thanks
