Hello I try to form a string to a json and I need to replace some chars in the request.

The error seem to at this part:  
from debug:

```auto
"rssi":"{WEB_MSG_STRONG}→9", (short version)
"rssi":"{WEB_MSG_STRONG}	9" (long version)

```

I already did this:

```auto
msg.payload = msg.payload.replace(/\n/g,"");
msg.payload = msg.payload.replace(/ /g,'');
msg.payload = msg.payload.replace('→','');

```

but the error remains.  
Thanks 4 ur help

The `→` indicates there is a tab character - `\t` in a regex.

```auto
msg.payload = msg.payload.replace(/\t/g,"")

```
