nodejs console.log doesn't print result if not in debug

Question

Not sure if it is bug or some hidden feature, but code below doesn't return anything if it is not in debugging. It supposed to return Hex buffer.

var fs = require("fs");
var d = fs.readFileSync("app.js");
console.log(d);

If I set break point on second line and debug - console.log prints buffer value.

Also all works if console.log(d.toString()).

I am developing in VSCode - may be bug with IDE?

Same code run as node app.js, outputs HEX buffer.

Any idea?

What do you use for debugging? I think that console log internally use util.inspect method. And this method can be customized. Maybe when debugging some customization is used? — Davide Icardi

Check now, added character encoding 'utf8'

var fs = require("fs");
var d = fs.readFileSync("app.js",  'utf8');
console.log(d);

with utf8 it works, same as .toString(). Quesiton is why vsCode doesn't show pure buffer
