Hi all, today, I was struggling with a fallback font I had defined, and I discovered that the key "check" doesn't work as I expected. Here's a small example: \definefallbackfamily [presentation] [serif] [TeXGyreTermes] [range=0x2329-0x232A,check=yes] \definefontfamily [presentation] [serif] [AntykwaTorunska] \setupbodyfont [presentation,12pt] \starttext (〈P〉) \stoptext With this input, the two characters 〈 and 〉 are not typeset; in the log, I find fonts > checking > char 〈 (U+02329) in font 'AntykwaTorunska-Regular' with id 1: missing fonts > checking > char 〉 (U+0232A) in font 'AntykwaTorunska-Regular' with id 1: missing If I have "check=no," the characters are taken from termes and replaced. I was under the impression that "check" should, well, check if the characters are not in the main font and fall back to the fallback font if they are not, but this doesn't appear to be the case. So what does "check" do? Or is this a bug? Have a great weekend Thomas
