Good day Disclaimer: I am a beginner, and I apologise upfront if there is a simple answer to this question that I should have known. Today I tried to compile an existing .tex file, and I received the following error message: /tex error on line 6 in file /Users/jjc/wrk/ctx/brx-test.pdf: ! String contains an invalid utf-8 sequence/ It's been about 3 weeks since I last experimented with ConTeXt. I am running on MacOS High Sierra 10.13.6, and I have not had an OS update since I last ran ConTeXt. I tried the following: 1) I tried to compile another file, which previously compiled successfully, and I had the same problem. 2) I then created a very simple .tex file (\starttext Hello World   \stoptext ), and again I had the same problem. 3) I checked the format of my .tex file in 2 different editors to ensure that it is utf-8. (I normally use MacVim and it is clearly displaying the file format as utf-8 at the bottom of the editor) 4) I updated my ConTeXt installation, restarted my Mac and tried again. The only difference was that some of the output stream was displayed after the error message. 5) I checked the log file for my simple file, but could not find any information to help me. The log file looks as follows: /open source     > level 1, order 1, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' system          > system          > ConTeXt  ver: 2018.09.13 17:41 MKIV beta fmt: 2018.9.17  int: english/english system          > system          > 'cont-new.mkiv' loaded open source     > level 2, order 2, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system          > beware: some patches loaded from cont-new.mkiv close source    > level 2, order 2, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system          > files > jobname 'tmp', input './tmp.pdf', result 'tmp' fonts           > latin modern fonts are not preloaded languages       > language 'en' is active open source     > level 2, order 3, name '/Users/jjc/wrk/ctx/tmp.pdf' tex error       > tex error on line 6 in file /Users/jjc/wrk/ctx/tmp.pdf: !
