Re: undefined control sequence bug with German umlaut in bibliography

I can also add that in the first case with the author name "Träger", the
generated bbl-file looks messed up and (Notepad++ doesn't recognize the
encoding as UTF8. Changing the encoding to UTF8 manually shows the complete
names "Träger" correctly, but the abbreviations (what should have been
"Trä06") seem to be messed up.

I'm not familiar with the intricacies and details of UTF8 encoding, but is
it possible that there is a byte missing from the "ä" which has been cut off
during the abbreviation process?

The abbreviated "Trä06" seems to be incorrectly encoded (in hexadecimal) as:
54 C3 A4 30 36,
while it should be: 54 72 C3 A4 30 36.

So in the abbreviation process, the encoding of some characters over several
bytes seems to be neglected.

I attached the bbl-files for both cases to this e-mail, since I don't know,
what would happen to the encoding, if I just pasted them as plain text here.
