AFAIK, "most other applications", at least those I could investigate,
come with fixed lists of fonts to use for each script.  These lists
are maintained for each OS and are adjusted as the OS version and the
fonts change.  This method has its advantages and also its
disadvantages; I think both are quite clear.

The rational thing to do is to use "C-u C-x =", see the script of the
problematic character(s), and then find and install some font that
covers those characters.
