Hmmm. That does not work for me (with any of many method and
transparency values). The ‘?’ is solid black. I do see a message
in the log that looks related:
mkiv lua stats > page group warning:
transparencies are used but no pagecolormodel is set
but adding \setcolors[state=start,cmyk=yes] does not
change that; both the warning and the solid black glyph remain.
Could this be an issue of the PDF viewer? Is it a font issue?
