All right. It was just an example. There are others, but you are aware of them, I see. I have made it such in my editor, that I may search for a glyph by some part of its name and then from a menu pick the one I want and then insert the escape sequence. The search, however, is not done in uniglyph.cpp(!), but in the font metrics files which then are not correct in all cases. Using the descriptive aliases instead of the hex code, do not work in other cases, so I can't have my cake and eat it too, it seems. Regards, Morten
