I exported CID fonts using ROS KOREAN-1-2.
There was no warning from Glyphs program in this process.
There is no problem in MAC OS, installation is good.
However, the Windows font viewer warns that it is not a valid font file.
It is not a long name longer than 20 characters, and ‘name info’ does not seem to be a problem for Windows.
Unlike OTF, TTF testing did not have any problems.
While searching for various problems, I deleted the features “vrt2” (Vertical Alternates and Rotation) and the problem disappeared.
Checking “vrt2 class” does not reveal any mistakes.
Would you mind cheking the file?
I will send the OTF and Glyphs files send at right now.
