Hello!
I have a problem with the export of the otf. form. It show “Could not translate UTF8 glyph code into Mac Roman in name table name”, when I export no matter what file, that I created. I think maybe, it is the problem from the software, but not from my file. Cause I’ve already tried to creat a new file then export again. But I still met the same error notification. Can perhapes anyone solve the Bug for me?
Thx for helping. 
This is probably one of the fields in File > Font Info > Font, perhaps the copyright notice or the manufacturer, etc. For the Mac table entries, the text needs to be reencoded as MacRoman, and it seems like there are some characters in one of your strings that do not fit into MacRoman.
Try emptying some of the fields before exporting, and see if you can find the culprit.
