Card Type

Hi,  Check includes/languages.asp - In the copy I have here the line to look for is :-
dictLanguage.Add "english_GateWay_12", "Card Type: "

BTW - I took a look at your site with Firefox & didn't see the "Â" when I got to the page.
 

It's a character encoding issue, for sure, but quite what's happening on your page I'm not clear.
Found on another site : 

The character  is 0xC2 in ISO-8859-1. It is also the first byte of the two byte encoding that utf-8 uses to express some characters. UTF-8 uses a single byte to express all characters with values between 0 and 127. Anything character from ISO-8859-1 that has a value between 128 and 255 requires two bytes to encode it. Anything between 128 and 191 (inclusive) will have a first byte of 0xC2, and if you read it as ISO-8859-1 instead of UTF-8, you will see a Â. What does this really mean? This is a Yen: "¥" This is a Yen, if you read it wrong: "Â¥" It looks fine, because in ISO-8859-1, a yen is 0xA5. And in UTF-8 a yen is 0xC2A5. So the character looks okay but there's junk at the start. Nonbreaking space is 0xA0 in ISO-8859-1, and when it comes up in UTF-8 it is 0xC2A0. This will look like " ". I used the Yen example above because it's easier to see something rather than just a space.

Even if the text in languages.asp looks correct in an editor it MAY contain hidden characters that are being displayed as a space in your editor, but as "Â" by the browser. Try putting a fresh, hand coped copy of the line in the languages file and deleting the existing copy. It's worth a try.
