PHP md5和JS hex_md5与特殊字符的结果不匹配

I have tried hashing a string in PHP7 using MD5 and the same in Javascript, but the results are different.. can someone explain me how to get this matched?

//PHP Code
md5('1: ÏtÚë£');

//Javascript Code
hex_md5('1: ÏtÚë£');

I expect the result to match, but the actual output are the ff:

PHP: "3fbee32d8a25287ad7ccbf133d82bb54"

Javascript: "9a7246843cd0c5906f2e588f0997116b"

Thanks in advance!

I don't know, what hex_md5() is (I can suggest it). Anyway, it's character encoding issue:

php/UTF-8:

3fbee32d8a25287ad7ccbf133d82bb54

php/LATIN-1:

9a7246843cd0c5906f2e588f0997116b
