It should be a PostgreSQL error message. Please try to use unicode data type (nvarchar/nchar) or use the correct charset to create the database if you want to use varchar/char data type. I have no idea about German special characters (I am a Chinese user). I think you should use try different iso-8859-x charset (from iso-8859-1 to iso-8859-15) because these charsets contains most of European characters in many languages.

You can find the list of PostgreSQL Character Sets in the following URLs:
http://www.postgresql.org/docs/8.0/interactive/multibyte.html
http://www.postgresql.org/docs/8.1/interactive/multibyte.html
http://www.postgresql.org/docs/8.2/interactive/multibyte.html
http://www.postgresql.org/docs/8.3/interactive/multibyte.html

Hope it may help you.

I am new to develop webapps with Gentle and ASP.Net.
When using Gentle 1.5 with PostgreSQL everything works fine if I do not use german special characters in string-values to store in database. If I try to store e. g. 'Bńrchen' into a varchar-field of the database I got the error message
FEHLER: 22021: ung├╝ltige Byte-Sequenz f├╝r Kodierung ┬╗UTF8┬ź: 0xe47263

How can I solve this fault?

Greetings Arne
