Hi Vincent,
these alternatives are only taken as a last resort before mentioning
that a glyph cannot be found. Unicode does list "minus" (Unicode: 2212,
MINUS-SIGN) to be related to "hyphen" (Unicode: 002D, HYPHEN-MINUS).
Otherwise, I wouldn't have made the change. The change is also not about
replacing minus for a hyphen, but for the other way around. I can of
course add a warning if an alternative glyph is used. But I guess some
people would find the warning welcome while others might find it a
nuisance. Can we get some additional opinions to reach an informed
decision, please?
Thanks for the explanation. I was also thinking about this yesterday
afternoon. I don't like the idea of the warning, because that makes
users think there is something wrong when in fact there isn't but maybe
an info level event instead to help make the process more transparent.
Does this glyph relationship apply to XSL-FO and SVG Text or just SVG
text? I think making the whole SVG Text process more transparent would
really help as it seems quite mystical. I know you made some further
notes on this process yesterday, but some more details about Font
substitution and glyph relations would be useful.
BTW, XEP does the same glyph substitution, so I guessed there must be
some standard dictating this behaviour.
Regards,
Chris

Log:
Added "minus" as an alternative for "hyphen" & Co.
Why? minus has nothing to do with hyphen, and the result is likely to
look terrible. I think I would prefer to have a warning rather than
a silent replacement. Anyway, if a font doesn’t even define a glyph for
hyphen, then I doubt it will define one for the true minus.
