Обсуждение: Unicode problems.

    Hi all,
  I'm trying to use the jdbc driver for postgresql to insert unicode
values in my database.

  I've got a table : test(test_field varchar(50)).
  I'm trying to insert and compare unicode string in this test_field,
but if I insert two different values ("\u2293", "\u2256") with a
PreparedStatement and a setString, the backend does not seem to make a
difference beetween those two values. If I try a Select from test where
test_field = ? and a setString(1, "\u2256") my result set gives me two
lines.

  Could someone please help me ?

  I compiled postgres with blcksz=32768 and the
--enable-multibyte=UNICODE option. \encoding returns me UNICODE
  I connect to the server whith jdbc7.0_1.2 (found at
jdbc.postgresql.org).
  I use the property charSet=utf-8 when making the connection
(info.put("charSet", "utf-8"); Driver.getConnection(db, info);)

Thanks.

Joel Seguillon.

Joel,

What happens when you do the select in psql ?

  Dave,
  When I try to select in psql it shows me some "?". (I use it on a
Linux console which can't represent those caracters i think).

    Tony,
  Je ne suis pas sur que cela resolve mon probleme. --enable-locale
n'est utile que pour visualiser les caracteres. Mon probleme principal
restera le meme, non ?

J'utilise un RedHat anglais sans locale=FR et ça marche

st_nazaire=# select * from questionnaire;

Retourne bien  ...informations sur la politique de la ville par rapport
à l'écologie

Je me suis battu avec ce truc et la sollution etait ca. multibyte et
locale. Perl ne semble pas avoir de problemes

A+
