To highlight words in multi-byte text:

<?php
$s
= 'Алабала';
$f = 'а';
echo
preg_replace('/('.$f.')/iu', '<b>$1</b>', $s);
?>

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:

<?php
function mb_str_replace($find,$replace,&$str)
{
$i = mb_strpos($str,$find, 0,"UTF-8");
if (
$index===false) {return;}
$str = mb_substr($str, 0,$i).$replace.mb_substr($str, $i+mb_strlen($find,"UTF-8"),mb_strlen($str,"UTF-8"));
$this->mb_str_replace($find,$replace,$str);
}
?>

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