When restoring a dump from sql_ascii encoding to latin9/utf8 the "THIS STRING|" result to "THIS STRINGŠ" thus it aborted the restore.
When I tried to dump a latin9/utf8 and restore it with the same encoding having same string it goes well but it took a very long time to copy all data. (1.6gb dump for 24/hrs)
So far I don't know what seems to be the problem why it took so long to copy the dump if it is already in latin9/utf8 encoding to latin9/utf8 database.
