AutoIt - Chrome native messaging host, character escape issue

I use AutoIt scripting language with Chrome browser for windows/web automation. I use a small program which called autoIt-chrome-native-messaging-host which communicate AutoIt program with Chrome. In the AutoIt code need to escape apostrophe and double-quote characters but in the messaging host escape to with a different way. I already found the way to escape the double-quote character but still have issue with the apostrophe character. I want to send back to the Chrome HTML code snippet which is contain apostrophe character but unfortunately I can't. Looking forward your knowledge.
