There is a similar discussion going on at the dejavu-devel mailing list.
There is interest from contributors to add glyphs for more languages,
like Arabic and CJK, as it has been with FreeFont which supports with
different levels of quality Latin, Central European, Cyrillic, Greek,
Arabic, CJK and perhaps more.
The issue arises from the fact that to use such a wide-coverage Unicode
fonts, one has to add high on the preference list
at /etc/fonts/fonts.conf
However, by doing so, other fonts are masked (hidden), such as Arabic
and CJK (Kochi).
Therefore, we have the interest of individual contributors to have their
script added or new fonts submitted that have partial support for some
scripts (for example, SIL Doulos has partial Greek support).
What is the best solution to solve this issue?
Is it to put restrictions to fonts? Some fonts are "semi-free", saying
you must not remove glyphs (so, Kochi Gothic cannot remove the bad Greek
support).
Or, should fontconfig be enhanced so that it allows a new configuration
option to mask/hide character ranges on specific fonts?
For the latter, there is a bug report waiting for developer love, at
https://bugs.freedesktop.org/show_bug.cgi?id=5987

Then please ask them to release DejaVuArabic, DejaVuCyrrillic,
etc.

There are several issues.  Most fonts that cover multiple
scripts, have ugly glyphs for all but one or two of them.  Or
they may simply not be my favorite ones.  And remember that
beautiful fonts for Arabic are among the ugliest for Persian.
Listing defects really doesn''t make much sense.  It''s like
bundling all GNOME apps together, saying you can either use all
of these, or none of them.

fontconfig configuration.  Fontconfig knows about languages, so
if SIL Doulos has partial Greek support, fontconfig doesn''t mark
it as supporting Greek, and so when some text is marked as Greek,
SIL Doulos will not be used to render that...  This support is
not perfect in the stack, but definitely improving.

No, I don''t think that bug is going to be resolved any time soon.
As I said above, it''s supposed to be already handled in another
way.
