syntax error when running IdentifyTranslate.js

[lee-zhg]

Tried to run code IdentifyTranslate.js for pre-webhook and received the error below:

ul 29 07:13:12 functions crn:v1:bluemix:public:functions:us-south:a/2c426324cc934f71a2a053c9185791ff::: {“error”:“Initialization has failed due to: SyntaxError: Invalid or unexpected token\n at initializeActionHandler (/nodejsAction/runner.js:63:80)\n at doInit (/nodejsAction/src/service.js:174:16)\n at initCode (/nodejsAction/src/service.js:93:24)\n at /nodejsAction/platform/platform.js:125:17\n at Layer.handle [as handle_request] (/node_modules/express/lib/router/layer.js:95:5)\n at next (/node_modules/express/lib/router/route.js:137:13)\n at Route.dispatch (/node_modules/express/lib/router/route.js:112:3)\n at Layer.handle [as handle_request] (/node_modules/express/lib/router/layer.js:95:5)\n at /node_modules/express/lib/router/index.js:281:22\n at Function.process_params (/node_modules/express/lib/router/index.js:335:12)“}

Weird invisible special characters caused the syntax errors. I got rid of the most of them except one. So, I had to remove it manually.

The code did not work even after removed the special characters. Code below is working on my system now. Thank you for the sample code.

BTW, I did not clone the repo. So, I won't create any pull request.
