strange characters in your filenames are never a god thing. But last time I had linux installed I had a variety of ftp clients. Maybe finding a replacement or too will do the trick.
The only one I remember the name of is iglooftp, under gentoo. To compile the latest one specifically for your pc type:
emerge iglooftp
and that should do it assuming they have it on thier database. Gentoo is sheer beuty, I aplaud your fine choice of OS.
