The mp utility supports all Asian locales. As a print filter, mp generates a properly formatted version of content in PostScript format. The Postscript output contains scalable or bitmap fonts, depending on the system font configuration formp in the current locale. The mp filter can print a ko file in ko locale or a UTF-8 file in the ko_KR.UTF-8 locale. For more information, see the mp(1) man page.
