[syslog-ng] Errorneous behaviour of syslog-ng v2.0.0 with logmessages in German

[Jewgenij.Belopilski at alumni.TU-Berlin.DE]

Hello,

I use syslog-ng v2.0.0 and observe the following erroneous behaviour:

If I specify a template for a target in syslog-ng.conf,
a log-message, which contains letters specific to German language
(Ä, ä, Ö, ö, Ü, ü), gets korrupted. Without specifying a template
all works fine.

The function in the source code, which corrupts log-messages
is
     src/templates.c::log_template_format(...)

Is this a bug?

I appreciate each help.
