Those files were 'fine' before today.

I know it is not a terminal problem --
I told ls to list all files in the directory -- then it says "no such file".

Can you say that "*" shouldn't match everything?

Those question marks are in the place for the size!

There are no weird characters in those file names.

Here are the same files in another directory:
mp3> ll 3*
-rwx------ 1 3255702 2010-06-14 10:54 30-Omoide to Yakusoku (TV saizu｜Reinaʼs Ver.).mp3*
-rwx------ 1 3272004 2010-06-14 10:54 31-Omoide to Yakusoku (TV saizu｜Tomoeʼs Ver.).mp3*
-rwx------ 1 3234876 2010-06-14 10:54 32-Omoide to Yakusoku (TV saizu｜Nanualʼs Ver.).mp3*


The fields it can't display are the file size, time and dates!  The names display ok!

How can file size, time and date be in unprintable characters that "ls" can't display?
