How to write json to file while keeping unicode characters on node js?

Question

JSON

Wrote on LAN (Windows 8.1) saves the file with all characters. After the transfer to the hosting (Centos 7) I began to save with "crakozyabry"
Code:

function updatePrice(body, startTimer){
var items = JSON.parse(fs.readFileSync('items.json', 'utf8'));
for (index = 0; index < body.items.length; ++index) {
    var price = body.items[index].price;
    var name = body.items[index].name;
    var idItem = find(items, name);
    if(~idItem){
    items[idItem].jar = price;
    items[idItem].ujar = new Date();
    }
}
  var items = JSON.stringify(items,"",4);
  fs.writeFileSync('prices.json', items);
  var elapsed = new Date().getTime() - startTimer;
  logger.trace("Обновлено "+index+" предметов");
  logger.trace("Время выполнения: "+elapsed+" мс.\n");
}

Name in items.json

StatTrak\u2122 AK-47 | Aquamarine Revenge (Battle-Scarred)

Output name in prices.json

StatTrakâ„¢ AK-47 | Aquamarine Revenge (Factory New)

Tried different encodings. Google suggests simply replacing these characters. I guess it's because of the operating system.
Node version on local 6.9.1, on hosting 6.11.0

Answer 1

Specify encoding explicitly
