Hi,

I suggest you to recreate database in WIN1521 encoding, so Java will not write unsupported characters. As well you can configure JDBC in way it will allow You to change client encoding, so you can change it to WIN. In both of above You will get error when you will try to write unsupported characters.

You may also do http://www.postgresql.org/docs/8.4/interactive/sql-createconversion.html

Hi all,

We have a product  with a PostgreSQLdatabase (unicode)
It has a (legacy) client app that uses client_encoding = win1521
The legacy app will be around for several years.
It cannot change to unicode.

There also is a new client app, written in java.
It uses client_encoding = unicode.

The problem: if someone inputs a non-win1252 character via the new
java app, the legacy app fails.
PostgreSQL returns an error: character blabla of encodig UTF-8 has no
equivalent in WIN1252.

What are my options to stop the legacy app from failing?
-Is there a setting to tell PostgreSQL to fail the character
gracefully by substuting it?

-Should i filter out all non win1252 charachters at the new java app
and substitute them? (not so nice, i'd like to have the chars in the
db)
-?more?

Greetings, Joek
