Perhaps the CSS text-transform: capitalize would work?

Use a function in a replace to change the strings:

HmtlStr = HmtlStr.replace(
  /([A-Z])([A-Z]+)/g,
  function(a,m1,m2) {
    return m1 + m2.toLowerCase();
  }
);

Edit:

The built in toLowerCase method handles most characters, you just have to include them in the set in the regular expression ([A-ZÖİŞÜĞÇ]) so that they are handled. To handle the few characters that the built in method doesn't cope with, you can make a function that replaces those first:

function localLowerCase(str) {
  str = str.replace(
    /İ/g,
    function(m){
      var i = "İ".indexOf(m);
      return i != -1 ? "ı"[i] : m;
    }
  );
  return str.toLowerCase();
}

You can easily add more characters for the function to handle by adding them in the /İ/ pattern, the "İ" string and the replacement in the "ı" string.

Try this one:

   'apple cat dog stack overflow'.replace(/(\b)([a-zA-Z])/g,
       function(firstLetter){
          return   firstLetter.toUpperCase();
       })

:)
