Björn, in one of our projects we are sorting in javascript in several languages 
English, German, Scandinavian languages, Japanese; from somewhere (I cannot 
actually remember) we got this sort spelling function for scandic languages

a
.replace(/\u00C4/g,'A~') //A umlaut
.replace(/\u00e4/g,'a~') //a umlaut
.replace(/\u00D6/g,'O~') //O umlaut
.replace(/\u00f6/g,'o~') //o umlaut
.replace(/\u00DC/g,'U~') //U umlaut
.replace(/\u00fc/g,'u~') //u umlaut
.replace(/\u00C5/g,'A~~') //A ring
.replace(/\u00e5/g,'a~~'); //a ring

does this actually make sense?
