Most libraries that don’t hold a lot of foreign language materials will be perfectly fine with ISO8859-1 ( also called Latin-1 or extended ASCII) encoding format, but if you do have a lot of foreign language materials you should choose UTF-8 since that provides access to a lot more foreign characters.

How do I change the encoding of a column in SQL?

The Process

1. Convert the column to the associated BINARY-type (ALTER TABLE MyTable MODIFY MyColumn BINARY)
2. Convert the column back to the original type and set the character set to UTF-8 at the same time (ALTER TABLE MyTable MODIFY MyColumn TEXT CHARACTER SET utf8 COLLATE utf8_general_ci)
