In case that can be expressed in not too technical terms: what's the  
difference between character and glyph? Character a logical unit (a  
Unicode code point, maybe) and a glyph a physical unit (ie a set of  
pen strokes)? It's not that important probably, but I'm just  
interested in understanding what you mean there.
