But if you're using a ligature or a digraph, it's better to encode it 
using the components rather than a new code — otherwise you'll be 
creating non-searchable documents.

The standard uppercasing of ß is two letters S, not one SS digraph. But 
as far as the capital ß is concerned, you can design it the way you 
prefer, but keep in mind that the very reason it was added is to provide 
a codepoint for encoding an uppercase ß which is visually distinct from 
two consecutive Ss.
