ess-tset in lyrics w/lilypond-book

[David Bobroff]

I've poked around trying to find a solution to putting an ess-tset
(scharfes 's') into some lyrics.  I get them in tempo markings without
any trouble (via LaTeX).

plain lilypond: \"s in lyrics makes 's' with umlaut
plain lilypond:  ß in lyrics works fine
plain lilypond:  \"s in \markup makes  ''s


I'm using 

\usepackage[german]{babel}

in my LaTeX wrapper file.  I get these results:

lilypond-book: \"s in lyrics makes 's' with umlaut
lilypond-book:  ß in lyrics makes nothing
lilypond-book: \" in \markup makes  ß

Is there a way around this?
