Glyph diff: Chrome may silently replace some glyphs by others

[madig]

I noticed that in the glyph-diff report, Chrome will display some glyphs like U+1FFD: GREEK OXIA and U+0385: GREEK DIALYTIKA TONOS using different glyphs if the originals with the needed codepoint aren't available, while Firefox won't. So if the old font has them but not the new font, you'll get a false no-diff report.

Not sure what to do about this.

ooooft. Thank you for bringing this to my attention. I'm pretty sure it'll be flagged as a missing glyph but it won't display as tofu.
