Hello, some of our fonts are having issues when exported and in OTF format and being used in our type tester which is supplied by http://www.type-applications.com .
The problem is the fonts ignore the kerning, guessing the error is to do with the GSUB or GPOS AFDKO or some exporting issue.
If we provided someone with a glyphs file that worked fine vs one that does not, would someone please be able to help spot the error and provide a fix?
We are willing to provide a small reward via PayPal if someone can fix this issue for us.
