        // remove any characters outside the valid UTF-8 range as well as all control characters
        // except tabs and new lines
        if ( !( (ch > 31 && ch < 253 ) || ch == '\t' || ch == '\n' || ch == '\r') ) {
            byteArr[i]=' ';
        }
    }
    return new String( byteArr );
}
