Hangul and Chinese

Hi,

I am interested in designing Hangul and potentially Chinese characters, but somehow I cannot work out how to find/add it to the languages.

Would be great if I could get a some advice on this issue.

You can add glyphs with the Font > Add Glyphs… In the text filed, you can add the uniXXXX names or directly type in the characters separated by a space.
If you need to add a set of glyphs to a font, make a list filter.
