    // %    note 1: Handles rare Unicode characters if 'unicode.semantics' ini (PHP6) is set to 'on'

    // *       returns 1: 'abcde'
    // *       example 2: substr(2, 0, -6);

    // *       example 3: substr('a\uD801\uDC00', 0, -1);
    // *       returns 3: 'a'
    // *       example 4: ini_set('unicode.semantics',  'on');
    // *       example 4: substr('a\uD801\uDC00', 0, 2);
    // *       returns 4: 'a\uD801\uDC00'
    // *       example 5: ini_set('unicode.semantics',  'on');
    // *       example 5: substr('a\uD801\uDC00', -1, 1);
    // *       returns 5: '\uD801\uDC00'
    // *       example 6: ini_set('unicode.semantics',  'on');
    // *       example 6: substr('a\uD801\uDC00z\uD801\uDC00', -3, 2);
    // *       returns 6: '\uD801\uDC00z'

// allow access of binary (see file_get_contents()) by: charCodeAt(x) & 0xFF (see https://developer.mozilla.org/En/Using_XMLHttpRequest ) or require conversion first?
