Thanks I will join this list as well and ask further questions there.

Good to know this.

That's why I am asking :-)

I understand this and now popups another question regarding this. In some

to make an invalid combination of characters render correctly. Obviously it 
has no source character. Shall I assign the next or the previous character?
