Avoid spelling checking superscript numbers

[a2937]

When generating a normal dictionary to see what was what; on the bottom of the list the following character was added
⁹.

As it is still a 9, I'd prefer to not to see it spell-checked please along with the rest of the numbers.

This should give you the list of characters to look for.
