Me too.  But as I wrote in my previous mail, this wasn't a change from
binary to ascii but only the 4 bytes that make file(1) think that it
is a binary font at the beginning of the file are missing now...

I'm not sure why we used .pfb in these symlinks (and in
fonts-urw-base35.scale) instead of .t1 extension.
Except this the symlinks are there because the X11 font path by
default point to
 /usr/share/fonts/X11/misc,
 /usr/share/fonts/X11/cyrillic,
 /usr/share/fonts/X11/100dpi/:unscaled,
 /usr/share/fonts/X11/75dpi/:unscaled,
 /usr/share/fonts/X11/Type1,
 /usr/share/fonts/X11/100dpi,
 /usr/share/fonts/X11/75dpi,
 built-ins

If we want to make fonts available to X11 we have to put them into
these paths (especially /usr/share/fonts/X11/Type1) place the
<package>.scale file into /etc/X11/fonts/Type1/ and run
 update-fonts-scale Type1;update-fonts-dir --x11r7-layout Type1;\
 update-fonts-alias --include /etc/X11/fonts/Type1/fonts-urw-base35.alias Type1
(via dh_installxfonts) in postinst to make all this available to the
font server.

So from my point of view we shouldn't remove the symlinks (since we
want to use these fonts in X11) but we should change the symlink
filenames from .pfb to .t1 and change urw-fonts-base35.scale
accordingly (hope that this works as expected, since I didn't try this
out yet).

Greetings
Roland
