What's the difference between utf8_general_ci and utf8_unicode_ci?

Question

Between utf8_general_ci and utf8_unicode_ci, are there any differences in terms of performance?

Answer 1

In brief words:

If you need better sorting order - use utf8_unicode_ci (this is the preferred method),

but if you utterly interested in performance - use utf8_general_ci, but know that it is a little outdated.

The differences in terms of performance are very slight.
