Selection to Word Caps - a PageSpinner AppleScript © Jerry Åman, Optima System 1997.
Converts the first character of every word in the selection to upper case and the remaining to lower case. You can add characters to upperTable and a matching entry in the same position in lowerTable to localize it to handle language specific characters, see an example ofhow to do this in Selection to lower case. The script is probably not compatible with languages such as Japanese, that uses 2-bytes ASCII.
