I am able to replace special characters, however when it happens it replaces them with "?". I basically want to replace the ä in this example with an underscore.

UPDATE: I do not want to replace all ä's, I only want to replace the first ä

$answer = "päivä";
$answer = substr_replace($answer, '_', 2, 1);
echo $answer;

Output: p�_ivä

Thanks :)

substr_replace() works on __byte offset and length__ not on character offset and length.... if you're working with a multibyte charset, one character is not one byte – Mark Baker Dec 23 '15 at 09:51

Have a look at http://stackoverflow.com/questions/1451144/php-multi-byte-str-replace. It might give you some clues. – Trevor Dec 23 '15 at 10:02
Hi, I do not want to replace all ä's, I only want to replace the first ä – jameswillis_ Dec 23 '15 at 10:14
What about [this](https://3v4l.org/DZA9Z)? – Narendrasingh Sisodia Dec 23 '15 at 10:20
Yeah thanks that helped! I still wanted to be able to select the letter so I added a line of code https://3v4l.org/SUN9H @Uchiha – jameswillis_ Dec 23 '15 at 10:33
