Re: Migrating from a 'big5' encoded DB to a 'utf-8' one.
Hi Leszek
If you set any options in my.cnf file please show it also.
Assuming that you didn't add any character set related option in my.cnf....

This should make all the character set variables to utf8 by default.

At this point, if you execute the following command:
mysql> show variables like 'char%';
It shuld be like:
+--------------------------+---------------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /path_to_the_charset_dir |
+--------------------------+---------------------------------------+
7 rows in set (0.01 sec)
> mysql> source backup.sql
So, when you insert the data from backup.sql mysql client thought "Oh, this file is encoded in utf8". But actually, the data is big5.
I think if you execute the following command and set the client character set variables to big5 before restoring backup data, it should work.
mysql> set names big5;
Can you try this?

Hmm, weird... Compiling --with-charset=big5 option should work ...
