Hello,  
I'm writing a code for sending SMS with Raspberry Pi and GSM USB dongle.  
I have a problem with inject node in writing a EOF character in JSON format. The flow is as follow:

```auto
[{"id":"d8eb11d.efd40f","type":"tab","label":"Flow 4","disabled":false,"info":""},{"id":"2832020b.e4752e","type":"debug","z":"d8eb11d.efd40f","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":510,"y":140,"wires":[]},{"id":"efc33395.0f617","type":"function","z":"d8eb11d.efd40f","name":"Send SMS Message","func":"var sms_msg = \"Hello world\";\n\nmsg.payload=sms_msg+\"\\x1A\";\n\nreturn msg;","outputs":1,"noerr":0,"x":320,"y":180,"wires":[["2832020b.e4752e"]]},{"id":"a2ffe2ca.7a614","type":"inject","z":"d8eb11d.efd40f","name":"Hello","topic":"","payload":"\"Hello world\"","payloadType":"json","repeat":"","crontab":"","once":false,"onceDelay":"1","x":130,"y":140,"wires":[["2832020b.e4752e"]]},{"id":"f1b5d379.20935","type":"inject","z":"d8eb11d.efd40f","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":"1","x":140,"y":180,"wires":[["efc33395.0f617"]]},{"id":"98b9e95c.90b698","type":"comment","z":"d8eb11d.efd40f","name":"Hello world\u001a","info":"","x":290,"y":220,"wires":[]},{"id":"d5fe7109.9e32c","type":"comment","z":"d8eb11d.efd40f","name":"Hello world","info":"","x":280,"y":120,"wires":[]}]

```

If I use the inject and function nodes, I can send EOF character successfully. But if I use inject node alone, I cannot get it work.

Any suggestions are greatly appreciated.

Regards,  
Aung

You can use \u001a as JSON only allow unicode escapes not hex.
