"HTML-like anchors" are only functional in WSL sessions. about terminal

Strangely, this does work within powershell:

gcc test.c -Wall -fdiagnostics-urls=always 2> warning.txt
type warning.txt

as does:
printf '\e]8;;http://example.com\e\\This is a link\e]8;;\e\\\n'
from w64devkit's shell.

Actually, this is probably GCC's fault somehow
It seems to be doing some weirdness here:
https://github.com/gcc-mirror/gcc/blob/21e7aa5f3ea44ca2fef8deb8788edffc04901b5c/gcc/pretty-print.cc#L661-L701

    /* If it is not a console, write everything as-is.  */
    write_all (h, read, strlen (read));

This would also explain why the redirection helps.

I did some more digging in GCC and there are multiple causes that result in this. It's not an issue with windows terminal, but I have some questions still. Can someone convert this to a discussion?
