Another interesting detail may be the computed value of 'font-family' in this test.

Like I wrote, it doesn't, the question was "should it [pretend to have an nbsp glyph]"?

> Unicode-range is not a claim of coverage. Its the inverse: its a claim of non-coverage of the space outside that range. (Which is useful, if the font does in fact have glyphs, but you don't want to use them, for example if they are ugly.)

What I meant was solely about the actual (nbsp) glyph, not about unicode-range.
