Hello!
I've written a Java desktop application which accesses a MySQL 5.1 DB running on a different machine (Ubuntu server 10.04). Clients run on Ubuntu 10.10
The "customer" is Slovenian. The DB is therefore UTF-8 and I connect to it using JDBC (class org.gjt.mm.mysql.Driver) and specifying
useUnicode=true&characterEncoding=UTF-8
in the connection url.
Data is read and inserted using stored procedures. Textual fields are VARCHARs.
Problem: all Slovenian characters are managed correctly (both read and written) except for c with the caron (unicode c48d). Whenever I try to insert this character from my application I get the error from MySQL stating that bytes c4 and 8d cannot be written in the involved column of the involved table. If I try to insert the character from, say, Query Browser, and then retrieve it, all works fine, though. If I read and then try to write what I just read, I get the usual error when saving!
I tried everything and can't think of anything more.
I've tried connector versions 5.1.8 and 5.1.18.
Below are the relevant (I guess) server configuration sections:
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
default-character-set=utf8
#character_set_results=utf8
#character_set_connection=utf8
[mysqld]
user = mysql
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
