ReferenceError: TextDecoder is not defined

[josemariagarcia95]

I'm trying to use this library to read data from a Xiaomi 2 Band with Node. I got a Bluetooth dongle and did several changes on the example code (since I cannot access Web Bluetooth from plain Node.js and the webbluetooth package doesn't seem to work at the moment). I can detect the device and presumably connect to it but I've stumbled upon this problem. When I try to create a new Miband object I get an exception from this line of miband.js (line 78).

this.textDec = new TextDecoder();
