Hi, gitk crashes when displaying a specific commit in the gnulib git repo.
How to reproduce: $ gitk Navigate to the commit 2995fb5e993a5d7434d96465758087b35a1488ac (title "unilbrk: Update handling of zero-width joiner for Unicode 10.0.0.") => 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: 12728 Current serial number in output stream: 12796 This is a known bug in the Xft library [1][2]. I noticed that it also happens for "regional indicator" characters. (Pairs of regional indicators render as a region's flag.) Sorry, I did not know about this bug before checking in the commit.
