Im having alittle trouble:

 

[A-Za-z]

 

I have the above regex to match letters, however they dont match special character letters like:

You will have to insert the unicode representative for that character in the character class

 

if (preg_match('#[A-Z\x{00FF}]#iu', $text))
{
echo 'Match Found';
}
else
{
echo 'Match No Found';
}

Or depending on which characters you wish to accept you could probably use a script.
