I have looked at all the threads that I can find with an issue regarding windows and I have tried them all. i.e. adding all the windows 1252 glyphs, making sure all the language-systems are defined, trying with and without auto hinting.
Sorry, “Showing Properly” means the glyphs are not being shown as per the rules in the OT features. Whereas the same combination of characters in mac osx shows according to the rules.
At the moment it is character set is Gujarati (planning on adding Devanagari), and the codes that are not working are:
rphf, rkrf, half, cjct, abvs and haln these are the ones that I am able to test as the other codes rely on these tables.
Did you write the feature code yourself or did Glyphs generate the code? Did you update the LanguageSystems and have set all scripts for the lookups correctly?
Can you send me the file?
Initially I let glyphs automatically create the feature codes, but wanted to show combining glyphs in a different way; which is considered, by some organisations, easier to read.
But when I realised it didn’t work in reverted and set all codes to0 ‘generate automatically’ yet it still didn’t work.
Also i did update the language systems, it seemed to have generated the languages as per the glyphs in the file.
