Motivation / Problem

When doing tests for #9443, I noticed weird output in the console.

After some digging and testing, it appears we convert internal UTF-8 strings to UTF-16 before outputting them. And it seems the output just stops on the first "invalid" char for the console codepage (I tried many codepage and was never able to print a string from greek translation).

While testing stuff, I also notice a nice crash with -q switch.

Description

Setting the console codepage to UTF-8 allows us to directly print the string without any conversion. Even if chars are not displayable by the console font, the string itself will be fully printed.

I also fixed the -q issue.
