注释

Note:

mb_regex_encoding()指定的内部编码或字符编码将会当作此函数用的字符编码。Warning

处理非信任的输入时从不使用e修饰符，就不会转码（即调用preg_replace()）。不注意这些会很可能会导致应用程序引发远程代码执行的漏洞。

To highlight words in multi-byte text: 

Transliterator for cyrillic-to-latin letters for UTF chars: 

when trying to find a way to strip newline from a multibyte UTF-8 string i got to this function just to discover later that POSIX don't "do" newline so i can't strip them, examples of what i tried are : \r\n , \\r\\n , (\\r\\n) (\\r|\\n) 
and got no result
so since i wanted something like mb_nl2br() that's simple i wrote this little recursive function for UTF-8:

note: moderate unit tesing was done, changed to other encodings
