I'm not shure if this is the problem fixed in mysql 3.23.18 with mysql = on client side but then I upgraded one of my servers to mysql 3.23.18 = from 3.23.16 I started to get the following messages then connecting to = mysql using mysql 3.23.16 library:

File '/usr/local/mysql/share/mysql/charsets/czech.conf' not found = (Errcode: 2)mysql: Character set '#2' is not a compiled character set = and is not specified in the'/usr/local/mysql/share/mysql/charsets/Index' = file ERROR 2019: Can't initialize character set 2 (path: default)

then I upgraded client to 3.23.18 the problem was gone, but still there = is something like capatability error....

The operating system is linux rh 6.2, the mysql was compiled with = default charset set to win-1251.
