PHP does not support Unicode character sets, so why is Unicode output correctly?

If it is a Chinese character, then it should not be the correct output ah. And for example, PHP file encoding is UTF-8, then the internal string type is also UTF-8?
My answer is not.
Since that string does not support UTF-8, why does it not appear wrong when it is displayed??

PHP file encoding is u8,string storage is also U8 Ah, do not believe you urlencode look at the good. If the charset of your page is set in Meta, U8 will certainly not show errors. You try to set it to GBK to see if he is wrong.

I think it refers to the unsupported is not a variable name, function name, parameter name it?
Unicode is stored as a string, but it's encoded. PHP does not parse and he doesn't have problems.
