I think browsers on Windows tend to have a hardcoded fallback to
"Arial Unicode MS" if all else fails. This font is commonly installed
on Windows, and covers all the Basic Multilingual Plane. But it is a
variable width font, so Emacs does not consider it a candidate when
looking for monospaced fonts.
