The BZ #2872 bug name is explicitly "Transliteration Cyrillic -> ASCII
fails". The ISO 9 System A does not map to ASCII so it is not a solution
to BZ #2872 at all.

I was scratching my head as to how can we avoid the explosion of the
scope for this patch. And then it appeared to me that it was wrong to
target all the present locales for the ASCII translit. This seems to be
the root cause for this prolonged A vs. B discussions. The proper target
for my table is actually the C locale translit file
(locale/C-translit.h.in). I will submit a proper patch shortly.

If anyone wants to keep working on the implementation of the Latin
Diacritics transliteration of the Cyrillic letters (System A) you are
welcome to use the tables I have submitted before (v9). That would be a
new feature for glibc as per my understanding. Let's just make super
clear the distinction of the System A (Latin with Diacritics, non-ASCII)
to the ASCII translit as mentioned in BZ #2872 (System B).

My focus is super sharp on helping with Cyrillic -> ASCII translit
availability for a default installation with glibc.

Hope this helps,
Egor
