This would only work on very recent version of Windows (I think Win10
v2004, maybe), and not very reliably.

However, you don't need the direct Win32 system call, you can use the
`chcp` command:


-- Set console output to UTF8
os.execute"chcp 65001"
-- print 'Ναί' (Greek 'yes') in UTF8
print(string.char(0xce, 0x9d, 0xce, 0xb1, 0xce, 0xaf))
-- print '番号' (Japanese 'no') in UTF8
print(string.char(0xe7, 0x95, 0xaa, 0xe5, 0x8f, 0xb7))


And there's still issues with input.

They may fix things in the future, or with a replacement terminal[1]
util. But who knows?
