The file with a strange name in this directory is no mistake.
It shows that Linux handles filenames in Unicode (UTF-8)
without ever realizing that they are in Unicode.
[However, some old tar's are unhappy with this filename.]
If you want to see it (the filename consists of two musical notes):
% setfont # load PC font, just to be sure
% setfont -u def.uni # load Unicode mapping table
% echo -e '\033%8' # set Unicode output mode
% ls -N # show filenames (raw)
% echo -e '\033%@' # set Latin1 output mode again.
If you want to remove it:
% rm ./??????
If you want to input Unicode:
% kbd_mode -u # Be careful! Do this only with a kbd_mode
# from kbd-0.88.tar.gz or later!
and next tell loadkeys what key combinations correspond to which
Unicode values. (See also the contents of that musical file.)
