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.

xerces23 is being removed, so I'm closing this bug.  The bug mentions
that KOI8-R support was broken after switching from the gnu transcoder
to the native transcoder.  Post-sarge, we will most likely provide
xerces only with the icu transcoder or, alternatively, continue to
provide native and ICU versions as we do now.  The icu version should
be used when non-builtin encodings are required.
