This github page adds ligatures to a font. Unfortunately when one creates a ligature where the "hidden" symbol contains many characters and the visible symbol contains a few symbols, a long trace of spaces replacing the missing characters is left behind.
For example, changing BigDelta to Δ results in something like
space-space-space-space-....-Δ
but the spaces are part of the ligature in the font.
It seems creating a ligature preserves the length of the string.That extension uses fontforge as I understand.
Are these trailing spaces at the back of the symbol an artifact of that extension or do all custom font ligatures do that ? Is there any way to remove those spaces ?
