Answer 1

I not have permission to comment, so I'll write my experience as an answer.

I have a problem with accentuated chars, solved puting '^' in the begin of regex and iterate each word of the text.

'^' indicates to match only the first char of word.

function captalize(s) {
    return s.toLowerCase().replace( /^\b./g, function(a){ return a.toUpperCase(); } );
}

var words = exampleText.split(" ");

jQuery.each(words, function(index, value) {
       var w = capitalize(value);
       exampleText.append(w).append(" ");
});
