Before this commit, the function (which allows adding unicode support
to a font definition) relied on the fact "serif" or "sans-serif" was
defined last in the given font. If that was not the case, you had to
give the position in the given font stack where you want to include
unicode support).
Now, if no position is explicitly given, the function does not suppose
"serif" or "sans-serif" is defined last. It only supposes it is defined
somewhere in the stack, and put unicode support just before.
