I've been interested in Unicode for many years, initially due to my interest in New Testament Greek corpus linguistics.
When XML came on the scene and I started running courses, I spent a lot of time making sure my description of Unicode (as it related to XML) was accurate.
I'm not a Unicode Master but I guess I'm a Unicode Journeyman :-)
