How to see cyrillic data in json use node.js restful API - node.js

Question

I have a cyrillic data in json format and in the API I see the data like this:
stations
0
Map_code 0
NAME_IME "Bjala river - Smoljan"
NAME_CYR "���� ���� - ��. ������"
Alertlevelwebsite 1
CODENUM 1
I want to display NAME_CYR "���� ���� - ��. ������" with UTF-8 or CP_1251 encode but I don't know how..?
The code:
app.route('/stations')
.get(function (req, res) {
// omitted
res.setHeader('Access-Control-Allow-Origin', '*', 'Cache-Control', 'private, no-cache, no-store, must-revalidate');
pool.query(`SELECT * FROM sel_alert_level s;`, function (error, result) {
if (error)
return res.status(500).json({ error: "Грешна заявка. Опитай отново !"})
stations = result;
res.json({ stations })
});
});
I try to put res.set({ 'content-type': 'application/json; charset=utf-8' }); before res.setHeader('Access-Control-Allow-Origin', '*', 'Cache-Control', 'private, no-cache, no-store, must-revalidate'); like this:
app.route('/stations')
.get(function (req, res) {
// omitted
res.set({ 'content-type': 'application/json; charset=utf-8' });
res.setHeader('Access-Control-Allow-Origin', '*', 'Cache-Control', 'private, no-cache, no-store, must-revalidate');
pool.query(`SELECT * FROM sel_alert_level s;`, function (error, result) {
if (error)
return res.status(500).json({ error: "Грешна заявка. Опитай отново !"})
stations = result;
res.json({ stations })
});
});
But this not work for me..

You need to check the headers from the response (use dev tools if you're using the browser). JSON is UTF-8 by default and if you use express it should be fine, but just double check.
If that doesn't work - use res.set({ 'content-type': 'application/json; charset=utf-8' }); (Express again).
