Package: libxerces23
Version: 2.3.0-2
Severity: normal

Hello.

After I upgraded xerces23 packages from 2.3.0-2 to 2.3.0-4 (as part of a
larger upgrade), I've got report from my users that their code that uses
xerces does not work any longer. After some inversigation, I found the
following changelog entry:

  * Switch from GNU transcoder to native transcoder

This looks to break KOI8-R support.

Minimal example code is attached, provided by one of uor users, is
attached.
