Dear Wolfgang, Yes, as you said, it is working. The current result of mtxrun is as following: Math-iMac:~ graph$ mtxrun --script font --list --all --pattern=georgia* georgia georgia /Library/Fonts/Georgia.ttf georgiabold georgiabold /Library/Fonts/Georgia Bold.ttf georgiabolditalic georgiabolditalic /Library/Fonts/Georgia Bold Italic.ttf georgiaitalic georgiaitalic /Library/Fonts/Georgia Italic.ttf georgianormal georgiaitalic /Library/Fonts/Georgia Italic.ttf I tested another english fonts whose name containing space by removing the space in the name when I call it. English fonts are working well. But the same file with the korean font is not working. As in the following log file, it loaded the fonts, but issue an error message. ############### ConTeXt ver: 2011.02.25 22:03 MKIV fmt: 2011.3.1 int: english/english system > cont-new.mkiv loaded (/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/cont-new.mkiv system > beware: some patches loaded from cont-new.mkiv ) system > testmp.top loaded (testmp.top) fonts > latin modern fonts are not preloaded languages > language en is active fonts > beware: no fonts are loaded yet, using 'lm mono' in box (/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/page-run.mkiv loading > ConTeXt Page Macros / Runtime Macros ){/Users/graph/ConTeXt/tex/texmf-context/fonts/map/pdftex/context/mkiv-base.map} fonts > preloading latin modern fonts (second stage) (/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/type-siz.mkiv) (/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/type-otf.mkiv){/Users/graph/ConTeXt/tex/texmf/fonts/map/dvips/lm/lm-math.map}{/Users/graph/ConTeXt/tex/texmf/fonts/map/dvips/lm/lm-rm.map} fonts > fallback modern rm 12pt is loaded system > begin file testmp.tex at line 29 fonts > otf loading > loading: /Users/graph/Library/Fonts/smHeadT Medium.otf (hash: smheadt-medium) fonts > otf loading > font loaded okay fonts > otf loading > loading method: table fonts > otf loading > file size: 1968816 fonts > otf loading > start enhancing: /Users/graph/Library/Fonts/smHeadT Medium.otf fonts > otf loading > warning: non unicode map '', only using glyph unicode data fonts > encoding > loading (extended) adobe glyph list fonts > otf loading > stop enhancing fonts > otf loading > saving in cache: /Users/graph/Library/Fonts/smHeadT Medium.otf system > logs > lua: compiling /Users/graph/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otf/smheadt-medium.tma into /Users/graph/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otf/smheadt-medium.tmc fonts > otf loading > preprocessing and caching took 0.578 seconds structure > sectioning > chapter @ level 2 : 0.1 -> X structure > sectioning > section @ level 3 : 0.1.1 -> One backend > xmp > using file '/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/lpdf-pdx.xml' pages > flushing realpage 1, userpage 1, subpage 1 pages > flushing realpage 2, userpage 2 system > end file testmp.tex at line 36 ) Fatal error occurred, no output PDF file produced! ############### I think that it is the only problem in Korean fonts whose name contaings a space. Thank you for your concern. Best regards, Dalyoung
