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:
