If I understand correctly, JDBC driver issues "set client_encoding to
iso-8859-8" in your case. You should check it first. If it does the
right thing, then you might want to the conversion maps. They are located:

src/backend/utils/mb/Unicode/utf8_to_iso8859_8.map    // UNICODE(UTF-8) -> ISO-8859-8
src/backend/utils/mb/Unicode/iso8859_8_to_utf8.map    // ISO-8859-8 -> UNICODE(UTF-8)

If you find anything wrong, please let me know.

Are you sure your client side display and fonts are set correctly? Can you look at the ASCII codes you get back from
Postgresto make sure they are not the correct Hebrew characters. You can send me some strings you got by email and I'll
lookat it if you want. 

Bye,

Guy.

Hi Elie,

actually it is much simpler if you use Unicode encoding on both sides.
Anyway, where do you see the strange characters? If you look at your DB
through commandline psql it is crucial to have the correct encoding.

I use to work on the commandline of my Linux box. I log in via putty,
which on a Win98 Machine is not capable of displaying unicode characters
correctly.

It's in utf8_and_iso8859.so.

> The second solution, that I prefer but that failed was to work server/client side only in utf8. The DB was UNICODE,
the'show client_encoding' returned unicode and the charset in the jsp was utf-8. Any idea !? 

In PostgreSQL, unicode, utf8 and utf-8 are all equivalent.

This is a Tomcat question...

When processing forms set the encoding of the form element using the
following attribute (in addition to all that you are doing):

enctype= "text/plain;charset=UTF-8"

eg <form action="blah" ... enctype= "text/plain;charset=UTF-8">

Also add a hidden field with special/accented characters in all your
forms. Query the parameter value (of the hidden field) in your
servlet/filter/jsp to see what you actually got. It could be that the
browser didn't respect your encoding, and you don't get back what you
put there in the first place!

Hope that helps.

you are working through the web. That makes the whole thing a lot more
complex. Try to use UTF-8/UNICODE encoding all the way. That means
configure Apache(!!!) and Tomact to server pages in UTF-8 encoding.
All web pages pages should have

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Check in your browser if UTF-8 encoding is used. On the other operating
system in IE use View > Encoding, it should show UTF-8.

Actually the browser to server communication is the hardest to ensure
the right encoding is used.

We have a database with Japanese, Hebrew, German, Swedish, French,
Spanish and English content.
