I received an email today which had a emoji on it's subject and every
time I tried to open it, X would crash. It took me some time to figure
out what was crashing X, and it was dwm.
If I try to open some window with this emoji '🏖' (U+1F3D6) on it's
title:
$ gvim '🏖'
dwm will crash with:
dwm: fatal error: request code=139, error code=16
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: 523
Current serial number in output stream: 538
I tried to just ignore this error on teh XErrorHandler, but it only made
dwm to stay crashed without exiting.
I did some research and other applications are affected. It seems to be
a problem with Xft and google noto fonts.
And there is this guy saying Xft is old and we should migrate to
fontconfig:

I could try to make a patch. What do you think?
