You can create composite fonts using one Roman font and one of the following Korean fonts:
Kodig-Medium-COMB-H
Kodig-Medium-COMB-V
Myeongjo-Medium-COMB-H
Myeongjo-Medium-COMB-V
For example, the following PostScript code defines a sample composite font, Times-Italic+Kodig-Medium, which uses Times-Italic for ASCII characters and Kodig-Medium horizontal font for Korean characters:
/Times-Italic+Kodig-Medium 13 dict begin /FontName 1 index def /FMapType 4 def /Encoding [ 0 1 ] def /WMode 0 def /FontType 0 def /FontMatrix [1.0 0.0 0.0 1.0 0.0 0.0] def /FDepVector [ /Times-Italic findfont /Kodig-Medium-COMB-H findfont ] def currentdict end definefont pop |
