Low-level Typographical Spellchecking: A Proposal

This article focuses on typographical spellchecking. Typographical spellchecking verifies the use of characters such as ? ! - ; : \sp $ @ and other special purpose characters in respect to spaces or null elements. The author claims that this kind of spellchecking has not been developed to any substantial degree, although it could be of considerable practical use as writer's aid. The article discusses the basic challenges of typographical spellchecking and shows that some of the difficulties are greater than might be expected at first sight. Rules for describing the behavior of typographical characters are proposed.
