what encoding stackoverflow used in mysql? -

I can not save the character in the encoding utf8 in mysql, but I think the stack overflow can save it and it Can display

I've made a mistake that Stackoverflow can not even save.

If you can not store the character, then you encoding or decoding it incorrectly, or it Converts a character set that does not support the character.

UTF-8 encoding can handle virtually any of the characters in any language, so it is not quite likely that it is a limitation encoding.

You have to use Unicode character set or some Unicode encoding (UTF-7, UTF-8, UTF-16, UTF-32) for all the steps in the process. If you change the text to another character set and then back, you can only support the characters in that specific character set.
