I'm adding a package repository in /etc/apt.sources.list.d/fffff.list.
The next run of apt-get update picks it up.
Afterwards, I'm renaming this file to ффффф.list, the cyrillic counterpart.
Now apt-get doesn't pick it up anymore.

The part before .list should be matched in a way that it extends to Unicode
alphabet characters. I don't see any technical reasons to restrict this part
of the filename to ASCII.

The relevant parts are the lines 340-347 in apt-pkg/sourcelist.cc; removing
them would make the algorithm accept all files ending in .list.

Hi,

I got bit by this same issue 10 years later.

The files in sources.list.d cannot have spaces in their names for this
same underlying reason.

This took a lot of time to figure out because this restriction doesn't
appear to be mentioned in the doc.

Regards,
Andrew
