JavaScript humanize method.

humanize.js

com = { cyberfox: {} };

/**
 * Convert a property name into a human readable string by replacing _ with
 * spaces, and upcasing the first letter of each word.
 *
 * @param {string} property The property name to convert into a readable name.
 * @return {string} The property name converted to a friendly readable format.
 * @private
 */
com.cyberfox.humanize_ = function(property) {
  return property.replace(/_/g, ' ')
      .replace(/(\w+)/g, function(match) {
        return match.charAt(0).toUpperCase() + match.slice(1);
      });
};

This do not match special characters (as they are not word)

Eg. furgão will become FurgãO

I ended using this version:

        return text.toString().toLowerCase()
                .replace(/[_-]/g, ' ')
                .replace(/(?:^|\s)\S/g, function(a) {
                  return a.toUpperCase();
                });

Just helped fix tons of IE8 errors. Thanks!
