Why should we use Character.toTitleCase() ? Why can't we use String's 
toUpperCase() ?

I don't see even java have solution for this ? can we just create map and 
lookup from it whenever these kind of char comes for conversion ?

Issue moved from commons-lang to commons-text, because WordUtils was ported to 
commons-text and and the commons-lang version will soon be deprecated.
