hi

I am actually not sure if this is a *my* problem or one of
Hibernate or PostgreSQL...but maybe someone experienced
can help me out ;-).

I created a PostgreSQL database (encoding UNICODE),
insert java string with (great) Hibernate and read the string
afterward a give them out on a HTML page with UTF-8
encoding. Things work quite fine, I can even insert arabic
or chinese messages and display them...

The only thing what doesn't work and I do not understand
is if I insert for example "German-Umlauts" (

The web app I'm working on currently is all done in UTF-8. I just checked the umlaut characters and they work fine. My guess is that your probably is related to the fact that these characters are part of an extended ASCII character set but that's just conjecture.

What phases are your data going through exactly between input and output? ie. is this a web app, swing, etc? What steps could be messing it up?

Try to experiment with driver versions, looks like custom converters are used by jdbc driver, it can be broken too.

Just for information:

I could finally manage by changing the default encoding of the
JVM (java -Dfile.encoding=UTF-8 ....)

PD:
Specifying the encoding in the jdbc url (..JdbcDriver?charSet=...)
didn't work out unfortunately...
