 * read.
 *
 * Therefore, instead of just using the UTF-8 codepage, this captures all reads
 * and writes to of_std{in,out,err} on the lowlevel, interprets the buffer as
 * UTF-8 and converts to / from UTF-16 to use ReadConsoleW() / WriteConsoleW().
 * Doing so is safe, as the console only supports text anyway and thus it does
 * not matter if binary gets garbled by the conversion (e.g. because invalid
 * UTF-8 gets converted to U+FFFE).
 * UTF-8 gets converted to U+FFFD).
 *
 * In order to not do this when redirecting input / output to a file (as the
 * file would then be read / written in the wrong encoding and break reading /
 * writing binary), it checks that the handle is indeed a console.
