I used `file in` node to read the **ini** file, but comparing the value of the readable line is not correct

```auto
var val1 = "[PATH]".localeCompare(msg.payload); // val1 = -1
var val2 = "[PATH]" === msg.payload; // val2 = false

```

```auto
[{"id":"f822faf5.cc3ea8","type":"file in","z":"aa40b590.ff1888","name":"","filename":"/Temp/Test.ini","format":"lines","chunk":false,"sendError":false,"encoding":"Shift_JIS","x":1500,"y":2420,"wires":[["d7be30e5.716ed"]]},{"id":"9cab729f.2d89f","type":"inject","z":"aa40b590.ff1888","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"str","x":1330,"y":2360,"wires":[["f822faf5.cc3ea8"]]},{"id":"d7be30e5.716ed","type":"debug","z":"aa40b590.ff1888","name":"result","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":1630,"y":2500,"wires":[]}]

```

How the comparison is please just help me!  
Thanks.

Trying comparing against `msg.payload.trim()` - that will remove the extra whitespace (my guess, a `\r` as you're on windows) that you can see in the Debug side view as.
