When I "Check Responses" after activating a WW problem,
there is an icon which does not render. This happens in the
showcase article:
Exercise 6.1: Answer Type Variety
https://pretextbook.org/examples/showcase/html/webwork.html#exercise-18
and also in MFG, which I just re-built:
Exercise 1.72: Practice 1
https://yoshiwarabooks.org/mfg/graphs-of-functions.html#exercise-173
The icon is next to the answer (whether correct or not). I think it is
supposed to be a "downwards heavy arrow". When I click it, the word
"correct" or "incorrect" appears below it. But I just see a placeholder
square, in Firefox and Chrome.
I know there has been discussion of fonts for icons, but I don't know
if that applies to WeBWorK.
