The “Autohint” feature in the edit mode context menu produces no results for the ‘o’ in my font (it produces results for all other glyphs). After manually adding vertical and horizontal stems in Glyphs (see image) the ‘o’ behaves as if completely unhinted when viewed in Indesign. I’m not getting any error messages at any stage.
Leaving the ‘o’ to be autohinted on export does result in hinting behaviour but the results are not desirable, hence the effort to manually hint the glyph.
Any idea why this might be happening?
