Is there a word that would refer to a number or a letter, but not any other character (like a comma or an exclamation mark)?

An alphanumeric character is one which is either alphabetic or numeric — that is, either a letter or a digit. As a noun, we can talk about alphanumerics for the collection of them, as I do here in this answer.
The term alphanumeric does not include punctuation, symbols, combining characters (like diacritics), spacing characters, or control characters.

@stephenwade You could just call them alphabetics, the way people call things diacritics (which are usually combining characters).– tchrist ♦Commented Mar 24, 2013 at 0:37

1Alphanumeric can be used as a noun, but mostly used by itself with the words character/field/string implied. Whereas, 'alphanumerics' is a collective term. Commented Mar 24, 2013 at 4:19
