I do know that IBM created DBCS well before the Unicode standard came about. I don't know if DBCS was ever an official standard supported by some semi-independent standards body or if it was just IBM. I also do not know if the character mappings are even close. I do know that DBCS has this concept of shifting in and out of DBCS mode and Unicode does not do that at all. So it doesn't look like they are particularly related. It looks like IBM was trying to find some way to add Unicode support and retain DBCS support for customers who have been using this for a long time. As the joke goes, "They wanted to do this in worst possible way ..."
