I am not sure what those numbers mean, since the obvious interpretations
leads to some contradictions :-)
First of all, 8r and 8y have the same overall glyph complement, so the
numbers must be wrong. Each inclludes the 15 glyphs missing from
Windows ANSI yet found in the standard 228 of typical text fonts.
Each also includes ff, ffi, ffl, dotlessj. So the +21 for 8r and +35 for 8y
should be BOTH +19 by my counting. I wonder whether you have
added into the 8y total the glyphs that are repeated for convenience?
As for conflicts, both 8r and 8y take the `standard' departure from
Latin 1 (and hence Windows ANSI) by replacing quotesingle in 39
with quoteright, and replacing grave accent with quoteleft in 92.
They also both have asciicircum instead of circumflex accent in 94,
and asciitilde instead of tilde accent in 126. So I count 4 conflicts
with Windows ANSI in *both* 8r and 8y.
Could you clarify your numbers please?
