[Mlterm-dev-en] Crashes with Noto Emoji fonts

[Yuri D'E. <wa...@th...>]

I'm increasingly finding emojis in git commit messages (!) and I was
trying to get something to show instead of an anonymous square block.

I tried to install the mostly black&white "Noto Emoji" font:

https://fonts.google.com/noto/specimen/Noto+Emoji

and map the emoji block with it ~/.mlterm/aafont:

U+1F300-1FADF=Noto Emoji

sadly it crashes on some glyphs (for example U+1f3b6 🎶) with the
following:

X Error of failed request:  BadLength (poly request too large or internal Xlib length error)
  Major opcode of failed request:  139 (RENDER)
  Minor opcode of failed request:  20 (RenderAddGlyphs)
  Serial number of failed request:  464
  Current serial number in output stream:  484

Aside from the crash, I'm not a fan of color fonts. I wonder if there
would be a way to force rendering to be grayscale and match my requested
foreground color as well.
