How can I debug a font's ligature glyphs?
For example, I have configured Iosevka with the following ligature:
[[iosevka.compLig]] unicode = 57673 # 0xe149 featureTag = 'XHS0' sequence = "->"
How can I view the glyph to confirm that
-> is being displayed as an arrow? Certain applications have their own logic, so I would rather see it in a font viewer in a more application-independent form if possible. For example, I would like to be able to confirm if a ligature does not exist.
