Yesterday, I started hacking on a new terminal emulator based on VTE.

  The reason is simple: There is none which suits my needs. And XTerm is
  causing  more  and  more  problems  because  it  doesn't  have   "font
  fallback",  i.e. it can't display glyphs which are not included in the
  primary font.

  As usual, my program is rather simple. Thus, it's already working  and
  I'm already using it.

  I  have not yet published it on GitHub, though. I want to use it for a
  while, iron out some potential bugs, and see if it's actually  a  good
  idea to do things this way.
