Hi,

some comments regarding the glyph:

* the bbox is too small horizontally (try viewing out/feta20.dvi)

* narrowing of the lines near the junction point is ok in principle,
  but I think the lines should be thinner still (the junction has more
  weight than the rest of the glyph)

* The glyph is quicker drawn by doing only upper right half, then
  doing

   addto currentpicture also currentpicture (yscaled -1);
   addto currentpicture also currentpicture (xscaled -1);

If you take these comments into account, I'll gladly merge a new
version of your patch.
