We have files that we have built in AI 2020 using the Raleway TrueTtype font. The client did not like the lower case "w" that crossed over in the middle so we replaced it from the glyphs with a more standard version. We have now released the files to the client & when they open the files in AI the "w" is reverting back to the original one they did not like. I don't know what version of AI they are using, & we sent them the same font that we used (we buy the licenses for them).
What could be causing the glyph to not work for them? Thanks!
