Dear Mojca, Thank you for the reply. As you did, I send my problem to the list. I think that I am a problem maker. I wonder why the output of XeTeX+ConTeXt was changed after the upgrade to Leopard. I didn't change anything in TeX system. I just upgraded the OSX. But nicely working XeTeX+ConTeXt had a problem with the korean commercial fonts.(no korean letters were appeared.) I installed TeXlive using i-installer(gwTeX) with Mac OSX Leopard, Latest stable ConTeXt, XeTeX 0.996 I made a short test file and a typescript file for the test. I have tested in several ways. 1. In XeTeX, everything is OK. Korean letters and greek capitals are appeared well. I thinkt that it used xdv2pdf. This is XeTeXk, Version 3.141592-2.2-0.996 (Web2C 7.5.6) file:line:error style messages enabled. entering extended mode (./test-font.tex [1] ) (see the transcript file for additional information) Mon Nov 5 16:56:15 graph.ssu.ac.kr xdv2pdf[21489] <Error>: WARNING: Type1 font data returned by OFAStreamPSDownload isn't in the correct format required by the Adobe Type 1Font Format specification. ... Output written on test-font.pdf (1 page). Transcript written on test-font.log. after adding \starttext and \stoptext 2. In XeTeX+ConTeXt, no ouput because of the korean commercial font. [1 ** NOTICE: This document contains a `Preview & Print only' licensed font ** ] ** ERROR ** CFF: Invalid character. Output file removed. Output written on test-font.pdf (1 page). Transcript written on test-font.log. 3.In XeTeX+ConTeXt without the definition of the korean commercial font: No error messeges, defined korean font and greek capitals are appeared well. But korean letters(except the manually defined korean font) are appeared as blanks. English letters are OK. 4. I used typescript file "type-xkor2.tex" No error message. English letters are OK. But korean letters(except the manually defined korean font) and the greek capitals are appeared as blanks. I think that Leopard has a problem with xdvipdfmx. It is just my guess. I attached test file and a typescript file. I used some commercial fonts but they are freely distributed as demo at the following site: "www.softmagaic.co.kr " After connecting it, you can see "otf sm font" in the third rectangle at the right side of the frame. You can download 5 fonts. I used three of them in the typescript file and one of them in the test file. Thank you again. Best regards, Dalyoung
