--- Comment #1 from Carlos O'Donell <carlos at redhat dot com> ---
The Cyrillic scripts are a big mess when it comes to the code pages used.

The CP1125 as defined in glibc is officially known as RUSCII, CP866U or GOST
Ukrainian [1]. It is considered one of the alternate encodings.

It is true that glibc's CP1125 is not the same as IBM's CP1125 [2] and again
not the same as IMB's DB2 CP1125 [3].

Some detailed discussions about the ambiguities can be found on FreeDOS'
discussion lists [4].

Therefore given that CP1125 is so poorly defined and what glibc has right now
is RUSCII and used by various Cyrillic languages I don't see us changing
anything to match IBM's own conflicting standards. I expect it has been copied
into ICU, libiconv and Python because Cyrillic authors find it a useful version
of CP1125.

Until we have strong reason to change this I'm marking this as
RESOLVED/WONTFIX. If you have a need for an official CP1125 then you will need
to determine which version you need and we can add another charmap.
