Well, the first problem is finding a charset or something that has a number
with a line over it and how you'd create that character in HTML, unless you
want to use an image or something.

Next, you can treat the result as a string and look at the last X digits. If
they are the same, remove them all and substitute with the number and a bar.
It just comes down to string manipulation...
