It fails to differentiate SSIDs with Unicode and ones without.

[issuefiler]

Expected behavior

WiFi.scan() should be able to differentiate the two SSIDs “🧊” (4 octets in UTF-8) and “F09FA78A” (8 octets).

Current behavior

> netsh wlan show networks

Interface name : Wi-Fi
There are 5 networks currently visible.

……

SSID 3 : F09FA78A
    Network type            : Infrastructure
    Authentication          : WPA2-Personal
    Encryption              : CCMP

SSID 4 : F09FA78A
    Network type            : Infrastructure
    Authentication          : WPA2-Personal
    Encryption              : CCMP

……

import WiFi from "node-wifi";

WiFi.init({iface: null});
console.log(await WiFi.scan());

……

    mac: '28:cd:c1:0e:50:82',

Which are the affected features

• node API
• CLI

Which is your operating system?

Windows

Environment

Windows

Version of node-wifi

2.0.16

Steps to Reproduce

Have two Wi-Fi access points with the different SSIDs “🧊” (4 octets in UTF-8) and “F09FA78A” (8 octets), and try scanning them with this Node.js package in Windows.

Solutions

By not relying on netsh and calling the native Wi-Fi Windows API instead.
