About invalid utf-8

[jawira]

Hello, I was just passing by and I saw your problem Invalid UTF-8 data in your README file.

After having seen your source code, I think the bug comes to the fact that your are using utf8 instead of utf8mb4. The problem is that MYSQL's utf8 uses only 3 bytes, while it should be using 4 bytes.

In practice this means you should be using utf8mb4_unicode_ci and not utf8_unicode_ci.

I hope this helps you.

Great research @jawira! I've updated the README with a link to that article too.
