UTF-8ify an existing MySQL database

First do

ALTER DATABASE database_name CHARACTER SET "utf8"; ALTER DATABASE database_name COLLATE "utf8_unicode_ci";

After that, for each table:

ALTER TABLE table_name DEFAULT CHARACTER SET "utf8" COLLATE "utf8_unicode_ci";

This just changes the default character set / collation for each table. To convert them, you need:

ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

By refactoring problematic code and creating automated tests, makandra can vastly improve the maintainability of your Rails application.
