If Character Set problems exist, the following errors may occur:
MySQL connection failed: the character set charset_name cannot be initialized.
Cause of the error:
· The multi-byte character set is not supported by the client. In this case, you need to run configure to recompile the client using the "-- with-charset = charset_name" or "-- with-extra-charsets = charset_name" options.
All standard MySQL binary files are compiled using "-- with-extra-character-sets = complex" and support all multi-byte character sets.
· The character set is a simple character set not compiled into mysqld, and the character set definition file is not in the expected position of the client.
In this case, you must take one of the following methods to solve the problem:
1. recompile the client to support character sets.
2. Specify the directory where the character set definition file is located for the client. For many clients, you can use the -- character-sets-dir option to complete the task.
3. Copy the character set definition file to the expected location on the client.
