Towards standards for handwritten zero and oh
Robert W. Bemer · Communications of the ACM · 1967
The Chairman of the ACM Standards Committee, Julien Green, has charged me with making “more effective use of CACM for communication … to get grass-roots opinions from the ACM membership.” This paper is the first attempt. A partial dossier on distinguishing between handwritten zero and the letter oh is assembled here. This presentation was triggered by a request for guidance in this matter presented by the United Kingdom Delegation to ISO/TC97/SC2, Character Sets and Coding, at the meeting in Paris on 1967 March 13-16. The matter is just now in the province of USASI X3.6, to which comments might be directed. Comments will be expected within sixty days [by approximately October 1st].
