if ( ch < ' '  || ch > '}' ) {
    // get the hex digit(s) of the character (either 1 or 2 digits)
    var hexCode:String = ch.charCodeAt( 0 ).toString( 16 );

    // ensure that there are 4 digits by adjusting
    // the # of zeros accordingly.
    while( hexCode.length < 4 )
    {
        hexCode = "0"+hexCode;
    }
    // create the unicode escape sequence with 4 hex digits
    s += "\\u" + hexCode;
} else {

    // no need to do any special encoding, just pass-through
    s += ch;

}
