CSS font matching does *not* require a system font fallback
procedure that searches all fonts for a given character.  Most
user agents support some form of default font mechanism which
allows a user to specify the font to use in the case of system
font fallback for a given language or character range. By
specifying fonts with full IVS support, users can achieve the
results you're looking for.  It's a good issue to bring to the
attention of various browser vendors but it's not a CSS issue per se.
