Peter asked:


Because in previous version the default encoding in mysql server is latin1 and not many remember to change it. So utf8 characters are saved in latin1 encoding. But what does this actually mean?

For example, some utf8 characters , which are not available in latin1, are 3-4 bytes long.

What binary data do they become after encoding them in latin1?

Thanks a lot.
Thanks for the link. But the link points to my own question.
