I was about to write "of course you can include an ASCII table, it's just a standard"... but then I went to the ISO website to check their copyright policy, and it says: "All content on ISO Online is copyright protected. The copyright is owned by ISO. Any use of the content, including copying of it in whole or in part, for example to another Internet site, is prohibited and would require written permission from ISO." But, it's not clear to me who actually owns the ASCII standard. Is it ISO? ANSI? I can't seem to figure out who, if anyone, holds rights to it. And, is ISO claiming rights to the standard itself, or just to their PDF documents describing them? These are all questions for a real lawyer who specializes in intellectual property, which I am most definitely not. The Wikipedia page for ASCII includes complete tables, so to be safe you could just link students off to it rather than copying the table into your course. Or to any of the other gajillion ASCII tables on the Internet. (In my opinion, it's extremely unlikely you would actually run into legal trouble by including ASCII codes in a course... but you never know.)
