23 | | * The Windows console does not do UTF-8. Bytes written to it, with |
24 | | * fwrite() or with WriteFile() alike, are decoded with the console's |
25 | | * output code page, so anything but ASCII comes out as mojibake unless |
26 | | * the user happened to run `chcp 65001` first. The wide character |
27 | | * console API is code page independent, so convert to UTF-16 and use |
28 | | * WriteConsoleW() instead. We must not call SetConsoleOutputCP(): the |
29 | | * code page belongs to the console rather than to us, so changing it |
30 | | * also changes the shell we were started from (see #1121 and #1184). |
31 | | * |
32 | | * Only a console needs this; a file or a pipe wants the UTF-8 bytes. |
33 | | * The is_tty flag alone cannot tell the two apart, as it is computed |
34 | | * once, from stdout, and passed along even for writes to stderr, so |
35 | | * ask the handle we are about to write to. |
