PHP preg_replace oddity with £ pound sign and ã
- by Barry Ramsay
Hello
I am applying the following function
<?php
function replaceChar($string){
$new_string = preg_replace("/[^a-zA-Z0-9\sçéèêëñòóôõöàáâäåìíîïùúûüýÿ]/", "", $string);
return $new_string;
}
$string = "This is some text and numbers 12345 and symbols !£%^#&$ and foreign letters éèêëñòóôõöàáâäåìíîïùúûüýÿ";
echo replaceChar($string);
?>
which works fine but if I add ã to the preg_replace like
$new_string = preg_replace("/[^a-zA-Z0-9\sçéèêëñòóôõöàáâãäåìíîïùúûüýÿ]/", "", $string);
$string = "This is some text and numbers 12345 and symbols !£%^#&$ and foreign letters éèêëñòóôõöàáâäåìíîïùúûüýÿã";
It conflicts with the pound sign £ and replaces the pound sign with the unidentified question mark in black square.
This is not critical but does anyone know why this is?
Thank you,
Barry
