change mysql default character set to UTF8 in my.cnf?
\nTo set the default to UTF-8, you want to add the following to my.cnf<\/p>\n
[client]\ndefault-character-set=utf8\n\n[mysql]\ndefault-character-set=utf8\n\n[mysqld]\ncollation-server = utf8_unicode_ci\ninit-connect='SET NAMES utf8'\ncharacter-set-server = utf8<\/pre>\n
