in reply to Can't write cyrillic to DBD::mysql

I'm not sure what is going wrong, and my experience with a DB holding non-ASCII characters is with Postgres and with Greek characters. Accordingly I can't give you answers but can recommend a few things which may help you with your debugging.

What is the value of $sql when you execute the third command?

Are you absolutely certain it contains UTF8 encoded Cyrillic characters?

If you read a Cyrillic string from your DB and then write it back to another location, does it get corrupted?

Is it only Cyrillic which is giving problems, or do other characters outside code page zero? (My guess is that they won't work either; try experimenting with Greek, Korean, or the like.)

Good luck!

    Hi Paul,

    Value of $sql seems fine (Below outputted by Devel::Peek).

    Test with Greek shows the same problem. String for Adresse2 is 'дц alpha beta'

    SV = PV(0xa494174) at 0x4df06fc REFCNT = 2 FLAGS = (PADMY,POK,pPOK,UTF8) PV = 0x9ea2894 "UPDATE users SET Adresse2='\303\244\303\266 \316\261 +\316\262' WHERE CONVERT( `users`.`Username` USING utf8 ) ='t est' LIMIT 1;"\0 [UTF8 "UPDATE users SET Adresse2='\x{e4}\x{f6} \x{3b1 +}\x{3b2}' WHERE CONVERT( `users`.`Username` USING utf8 ) ='t est' LIMIT 1;"] CUR = 101 LEN = 104

    But what does that tell us?

    Still confused
