问题
Where do I find a list of character sets that are equal in the WHERE clause?
Background: The list of characters may be used to solve a problem mentioned in another question.
(Also interesting, but not necessary for an answer: Is this collation fixed forever, or are future changes expected?)
回答1:
I have found this tables: http://developer.mimer.com/collations/charts/index.tml. They are, of course, landuage dependant. Collation is just comapring algorithm. For general utf8 I am not sure, how it treats special characters.
Another resources:
http://collation-charts.org/
http://mysql.rjweb.org/doc.php/charcoll (down on the page)
and of course http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-sets.html
Basicly, try to google "collation algorithm mysql utf8_general_ci" or something like this
