Re: [dev] [st] Cannot display unicode characters for example '\U1F50D'

I'm also using Monaco for xfce4-terminal. But I guess xfce4-terminal
implicitly handles unicode symbol errors and such. I'll try to try out
every fonts in my cache, but it would be exhausting.

By the way, I tried to launch st from another st instance and did
`echo $'\U1F50D'`. The new st instance crashed and the output in the
old st instance was 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: 1353
  Current serial number in output stream: 1392

Maybe this error catch could provide some insight?
