Answer 1

You could use a unicode character class http://www.regular-expressions.info/unicode.html

preg_match("/\p{Han}+/u", $utf8_str); 

This just checks for the presence of at least one chinese character. You might want to expand on this if you want to match the complete string.

Answer 2

@mario answer is right!

For Chinese chars use this regex: /[\x{4e00}-\x{9fa5}]+/u

And Don't forget the u modifier!!!
