This is painful for developers.  I think it's the reason almost
all the GUI software for GnuPG doesn't handle Russian UID's correctly.
(Examples: kmail and kgpg.)  These programs are all written with
libraries that love raw UTF-8, but GPG is forcing these developers
to hand code an extra level of nonstandard decoding.  (Actually, it's
not, most programs appear to be skipping the step and just giving the
end user garbage.)

Here's some QT code that gets around the problem.

//  GPG escapes certain UTF-8 characters in UID's with '\xHH'. The
//  following replaces '\xHH' sequences with the unicode character
//  represented by hex 'HH', then we convert from UTF-8 to QT's
//  unicode format.
void GpgParse::decodeUID( QString &s )
  QRegExp rx( "\\\\[xX]([0-9,a-f,A-F]{2})" );

  int pos = 0;
  while ( (pos = ( s, pos )) >= 0 ) {
    QChar c( rx.cap(1).toUShort( NULL, 16 ) );
    s.replace( pos, 4, &c, 1);

  s = QString::fromUtf8( s, s.length() );

I'm attaching my public as well, since it makes a good test case.
