As a general comment, sorting a string does not make sense in general 
when Unicode is involved. For example, there may be combining diacriticals:

     // Three characters: e, a, and combining acute accent U+0301
     writeln("eá".array.sort);

prints

aé

So, the accent moves from a to e, which probably is not the intention.
