Description
Originally Fira Code uses scheme with spacer + single-space ligature that extends beyond its bounding box:
This was done to allow editors to “step inside” the ligature.
Since the original release, many editors now acknowledge the existence of ligatures and don’t need that trick. Maybe ligature code could be simplified?
Potential upsides:
- Much simple ligature code
- Ligatures could be assigned code points and used in e.g. Emacs #211
- Fix ligatures inside RTL
Questions to check:
- Check which editors will not “step into” ligatures
- Check if Linux will be ok with double-, triple- etc size glyphs #1073

Research direction
Start by investigating which editors do not step into ligatures and whether Linux supports double-, triple-, and larger-size glyphs, as listed in the issue. Review the existing ligature scheme, along with the related concerns in #1073 and #211; done means the compatibility questions are answered and a simplified scheme is specified.
