That article raises an interesting issue about a character in the author's name that is missing from Unicode. Unfortunately the article is (how to put this?) not constructive. The complex reasons that Unicode excluded the character are described in [1]. If the author addresses those issues, there's a much better chance to get the desired character into Unicode.
