How to read a file in utf8 encoding and output in Windows 10?

What is proper procedure to read and output utf8 encoded data in Windows 10?

My attempt to read utf8 encoded file in Windows 10 and output lines into terminal does not reproduce symbols of some languages.

OS: Windows 10
Native codepage: 437
Switched codepage: 65001

In cmd window issued command chcp 65001. Following ruby code reads utf8 encoded file and outputs lines with puts.

fname = 'hello_world.dat'

File.open(fname,'r:UTF-8') do |f|
    puts f.read
end

hello_world.dat content
