Re: [csswg-drafts] [css-values] ch units shouldn’t cause font downloads

Because all fonts are required to have one.

No, it is typically a rectangle (and, I think, typically uses the default advance width)

>> It is recommended that the shape of the .notdef glyph be either an empty rectangle, a rectangle with a question mark inside of it, or a rectangle with an “X”. Creative shapes, like swirls or other symbols, may not be recognized by users as indicating that a glyph is missing from the font and is not being displayed at that location.
