I opened it (Mint 19.3/64b) in qpdfview and evince, print out by pdfinfo and mutool and in all cases there is "a b c" or "a, b, c" (, = single left quote) as was written. (My acroread is just broken and in xpdf and mupdf I guess there is no service to display it.) What is the reason that keyword attribute does not accept commas whereas others (title, author...) do? # keyword={{a, b, c}}, As far as I know, key words (in papers, books etc.) are used only as a comma separated list of terms without further structuring so I cannot imagine who and why would need braces in normal cases.
