Can you say anything about the character sets you are using?
 [2009-09-20 22:44 UTC] grzegorz at heex dot pl 
Column lng_name and a whole table they have utf8_general_ci charset.
 [2009-09-22 13:53 UTC] uw@php.net 
Ok, great. Your character set is uft8 (uft8_general_ci is the collation). 

Can you paste "SHOW VARIABLES LIKE '%character%'" to give details about your MySQL settings?

Thanks!
 [2009-09-22 16:35 UTC] grzegorz at heex dot pl 
Variable_name 	Value
character_set_client 	utf8
character_set_connection 	utf8
character_set_database 	utf8
character_set_filesystem 	binary
character_set_results 	utf8
character_set_server 	utf8
character_set_system 	utf8
character_sets_dir 	C:\Program Files\MySQL\MySQL Server 6.0\share\char..
 [2009-09-22 17:00 UTC] uw@php.net 
Thanks again, utf8 everywhere. We guessed so. 

I don't know if its of much relevance but one last question: what version of MySQL 6.0 are you using?

.oO( MySQL 6.0 is something I don't like to see here. I wouldn't want to debug a non-GA server, if I had a choice. )

Thanks!
 [2009-09-22 18:58 UTC] grzegorz at heex dot pl 
It's 6.0.5-alpha-community
 [2009-11-04 17:11 UTC] uw@php.net 
If its not crashing with MySQL 5.1, I strongly believe this is a MySQL matter not a PHP problem. Can you try 5.1? 

Thanks

OK, I've downgraded my MySQL to 5.5 and now it's fine.
But bug of PHP 5.3 and MySQL 6  is still open.
 [2010-01-04 10:56 UTC] uw@php.net 
MySQL 6 is not GA, MySQL 6 bug
