Part of the problem is that clear, coherent explanations of ISO 2022
are hard to find. I have put together one myself, based entirely
on what I have been able to glean from reading code and searching
the Web, as a part of implementing ISO 2022 in the ASCII-font
program FIGlet (

I don't want to burden the Unicode list with the text, but I would
like someone (or ones) to review it. Any volunteers?
(The text is about 600 words long.)

ObUnicode: FIGlet uses Unicode internally and understands UTF-8
