Dear Wolfgang,

Two months ago, you suggested an example for typefile with korean. I just read it at that time and I try your sample today. 
Although there are Nanum Gothic and Nanum Gothic Coding in my system font, no output of korean for \ss and \tt.
I run ‘mtxrun —script font —reload —force
in the terminal, but the output is same. In the log file, it reads that 

selectfont      > The requested fallback font 'Nanum Gothic' for typeface 'mainface' style 'ss' was ignored because no files where found.
selectfont      > The requested fallback font ‘Nanum Gothic Coding' for typeface 'mainface' style 'tt' was ignored because no files where found.


Why ConTeXt couldn’t locate the font files?

I am using Mac OSX 10.13 and latest beta.

Thank you.

Best regards,

Dalyoung

You need fonts [1-3]  which contains hangul characters (don’t forget to 
set a math font because it is used for the symbols in enumerations) and 
you have to enable linebreaking for korean with the \setscript command.

%%%% begin example
\definefallbackfamily [mainface] [rm] [Nanum Myeongjo] [preset=range:korean]
\definefontfamily     [mainface] [rm] [DejaVu Serif]

\definefallbackfamily [mainface] [ss] [Nanum Gothic] [preset=range:korean]
\definefontfamily     [mainface] [ss] [DejaVu Sans]

\definefallbackfamily [mainface] [tt] [Nanum Gothic Coding] 
[features=none,preset=range:korean]
\definefontfamily     [mainface] [tt] [DejaVu Sans Mono] [features=none]

\definefontfamily     [mainface] [mm] [DejaVu Math]

\setupbodyfont[mainface]

\setscript[hangul]
