db collation mysql code example
Example: database collation mysql
The main difference is sorting accuracy (when comparing characters in the
language) and performance. The only special one is utf8_bin which is for
comparing characters in binary format.
utf8_general_ci is somewhat faster than utf8_unicode_ci, but less accurate
(for sorting). The specific language utf8 encoding (such as utf8_swedish_ci)
contain additional language rules that make them the most accurate to sort for
those languages. Most of the time I use utf8_unicode_ci (I prefer accuracy to
small performance improvements), unless I have a good reason to prefer a
specific language.
You can read more on specific unicode character sets on the MySQL manual -
