[issue43647] Sudden crash on print() of some characters

Excellent investigation!

Idle automatically picked Dejavu Sans Mono as default font. I have also several fonts for e.g. unicode symbols and emojis installed. Noto Sans Mono CJK fonts are working fine, too. However when I select the Noto Emoji font in the font selector, Idle immediately crashes with a very similar Xlib error

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:  12760
  Current serial number in output stream:  12769
