Optical alignment of alternative glyphs [Publisher]

[Evgenii]

The font I'm using is having an alternative period at the end of the paragraph (three dots vs two dots on the image below; the substitution is defined in opentype feature, three dots period is an .alt glyph). While all standard punctuation is hung without issues, the alternative variations are not recognised. I cannot copy-paste it into glyph section of optical alignment of Character Panel, and I cannot insert it there from glyph viewer either. Is there any workaround?

Hi Evgenii,

If possible could you provide the font in question and a copy of your document so I can look into this further for you.

Thanks
