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.
