How can I debug a font's ligature glyphs?

For example, I have configured Iosevka with the following ligature:

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.

  1. Open Font Manager.
  2. Select your font.
  3. Click Preview.
  4. Click Ab to make the preview font editable.
  5. Enter your potentially ligated string into the preview box.
  6. Visually confirm or deny the presence of a ligature.
