As is left-hand traffic in right-hand traffic countries or vice versa.
There are many different approaches to deal with this:

 - for a small amount of files I'd say it is normaly safe to ignore it
   (though that does not seem to be the case here)

 - put parts with architecture-independent data to /usr/share and
   symlink them. That is what usually takes the last efford and when
   directories are at least locally consistent (like images in a
   images subdir) can be relatively good. Having to sort things on
   a per-file basis can be ugly, though...
   Depending on the data, also the other way around is possible, i.e.
   having everything in /usr/share and only sorting the architecture
   dependent data out and putting that in /usr/lib.

 - patch the program to look in multiple places. How easy or difficult
   this is depends on how it is implemented. If every file is looked
   for in a search path, the search path could simply also contain
   the /usr/share directory. When things are searched relatively
   to other stuff (like a image in the same directory as a library,
   or first searching the plugin dir and than looking for stuff in
   there), things get more complicated, but sometime can still be
   relatively easy. (If you know that only shared libraries are
   architecture dependent and everything else is not, for example,
   an (slighly ugly, but very effective) way might be to just
   try again a dl_open again with lib replaces by share if the first

I don't know what is necessary here, but I'd strongly recommend to find
a way to use the normal fonts. Also fonts that are not yet in Debian
might be able to be included in Debian as seperate packages, so also
other software can benefit from it. (And when it cannot, it most likely
might be problematic in this package. Font licenses tend to be seldom
looked at and often very strange). I think in this case it would be
really be best if there was a way to have the global fonts used without
having to create symlinks, as I guess symlinks might easily break in
the long run.
