Strange MySQL / sqlite3 Problem with unicode

[Hans Müller]

I have a strange unicode problem with mySQL and sqlite.

In my application I get a table as a sqlite table which is being compared to an existing mySQL Table.

The sqlite drive returns all strings from the table as a unicode string which is Ok.
The mysql drive returns all strings as utf-8 coded strings (no unicode!).

When opening the mySQL database, use unicode is set to true, so the driver should return
unicode strings.

Any ideas ?

This is the mySQL table definition:
CREATE TABLE `USERNAMES` (
   `NAME` varchar(256) COLLATE utf8_bin NOT NULL,
   `ID` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
   PRIMARY KEY (`NAME`),
   KEY `BYID` (`ID`)
) ENGINE=MyISAM AUTO_INCREMENT=59325 DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='Table for mapping user names to IDs'


The sqlite Table was created this way:

sq3Cursor.execute("create table USERNAMES(NAME text, ID integer)")

When I query a value from both tables I get:

sqlite:
 >>> SrcCursor.execute("select * from USERNAMES where ID=49011")
<sqlite3.Cursor object at 0x2b6096bfc240>
 >>> SrcCursor.fetchone()
(u'J\xd6RG R\xd6\xdfMANN', 49011)
 >>> print u'J\xd6RG R\xd6\xdfLER/BD_FH'.encode("utf8")
JÖRG RÖßMANN

This is Ok.

Now mysql:

 >>> DstCursor.execute("select * from USERNAMES where ID=49011")
1L
 >>> DstCursor.fetchone()
('J\xc3\x96RG R\xc3\x96\xc3\x9fMANN', 49011)
This is the same result, but returned as a utf-8 coded string, not unicode
 >>> 'J\xc3\x96RG R\xc3\x96\xc3\x9fMANN'.decode("utf8")
u'J\xd6RG R\xd6\xdfMANN'


The mySQL database has been opened this way:

DstCon = MySQLdb.connect(host = DstServer, user = config["DBUser"], passwd = config["DBPasswd"], db = DstDBName, use_unicode = True, charset = "utf8")
DstCursor = DstCon.cursor()

Since use_unicode is set to True, I expect query results to be unicode (for string data types).
