Your program uses an incorrect path to determine where the character sets are stored. (Default /usr/local/mysql/share/mysql/charsets). This can be fixed by using the --character-sets-dir option when you run the program in question.

The character set is a multi-byte character set that cannot be loaded dynamically. In this case, you must recompile the program with support for the character set.

The character set is a dynamic character set, but you do not have a configure file for it. In this case, you should install the configure file for the character set from a new MySQL distribution.

If your Index file does not contain the name for the character set, your program displays the following error message:

ERROR 1105: File '/usr/local/share/mysql/charsets/?.conf'
not found (Errcode: 2)

In this case, you should either get a new Index file or manually add the name of any missing character sets to the current file.
