Problem with command tr

Hello, excuse me for my english, i'm a french man.

I have a problem with the command tr in applescript (with the accent...in french we have a lot of accents), i have read that is a problem with the version 10.5 of leopard then i would want to download the version 10.4 of universal binary of tr but i don't find the link...

Thanks...

Nobody has an idea, it's too bad...
