[Pkg-fonts-bugs] Bug#411909: ttf-dejavu: wrong instructions for some glyphs used in Kazakh text

[Davide Viti]

Package: ttf-dejavu-udeb
Version: 2.14-2
Severity: important
Tags: patch, pending

Some Kazakh letters are rendered differently when using ttf files from the udeb;
it turns out that is caused by stripping the following range out of the udeb:

* IPA Extensions (U+0250-U+02AF)

this can be seen in [1] where the left image shows text rendered using 2.14-2, while
the right side shows how the image differs from the same text rendered with 2.13-1
(which is shown in [2]). The patch below fixes the problem.

I spent a lot of time making sure there are no more regressions due to mising ranges, and 
in particular I tested:

deb vs. udeb (i.e. unstripped vs. stripped)
latest upstream experimental package vs current 2.14-2 (both debs and udebs)

and I'm confident there are no other problems.

Regards,
Davide
