It's because numbers are reserved for questions. A question URL is of the form /qa/123 so you can't have a category "123" because the category should be at /qa/123 also.

I assume that any letter in there would be fine, or any punctuation mark not listed above.

You are right, adding a c1, c2 is fully sufficient... I know it is not the nicest for seo, but as I have 3 levels only the last one has a nice slug, so urls do not become too long.
