Re: how to change unicode string to byte array ?

[moritz]

Sorry, your description is too cluttered and not very good readable (did you read Writeup Formatting Tips?) to make sense to me.

But there are a few things you should know: You can downgrade your string with Encode::encode_utf8 into a "byte string", the reverse function is decode_utf8 in the same module.

What happens to the strings inside your database is subject to the DB configuration and the options to the DBD module you're using (DBD::mysql probably).
