Very many.  RFC 1345 defines a set of digraphs (i.e., pairs of
characters representing another character)

http://rfc.net/rfc1345.html

which one can use.  Vim implements it with a simple array of structs like

typedef struct digraph
{
 char char1;
 char char2;
 char substitution;
} digraph;

http://vim.cvs.sourceforge.net/vim/vim7/src/digraph.c?revision=1.9&view=markup

Anyway, RFC 1345 defines about 1950 such digraphs.
