Problem solved. The superfluous line at the top of the file ["Binary file (standard input) matches"] isn't stderr, it's stdout, so it becomes part of the pipeline. The grep in pdfmom is returning a binary file hit when it encounters the diacritic in .ds pdf:look(pdf:bm1) L'étranger Since the binary file hit doesn't begin with .ds, it prints literally at the top of the file. The solution is to pass the -a flag to grep. Deri: do you want me to fix this in pdfmom and push the change, or would you prefer to do it yourself? Question: why does grep treat the presence of the diacritic as cause for saying "Binary file (standard input) matches"? -- Peter Schaffter http://www.schaffter.ca
