I've found that this bugs affects applications other than gitk.
I'm developing an FLTK application in Rust, and I get the same problem when my app displays a list of emojis (via hold browser widget).
Regarding the solutions:
- installing `unifonts` had no effect
- installing `fonts-symbola` had no effect
- uninstalling `fonts-noto-color-emoji` solved the problem, although the emojis are printed in black and white, and are very difficult to recognize; additionally, it breaks other apps (e.g. MATE terminal)
