I tried to test it with the code below, but then it selects the stixtwomath
glyphs. So possibly the force override is used only if the font has the glyph,
instead of giving an error.
\definefallbackfamily [mainface] [math] [stix]
[range={00B2-00B3,00B9,02070-0208F},force=yes]
\definefontfamily [mainface] [math] [stixtwomath]

Perhaps the stuff that the PDF displays may not need to be what one copies, that is, it displays something that looks good, but when coping as plain text, one gets something that is useful. That is possible for HTML URLs, even though it is a security hazard for such links. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Maybe as a part of general features: A font fallback that selects the character
from a sequence of fonts if not available, which could involve ranges, too, but
not necessarily. And being able to have untranslated throughput.
