Ok, sounds good. Also, you don't have to actually tag people by name for every comment. It's only really useful if multiple people are talking or the person has not been subscribed to the issue. The first time you mention them or they reply to the issue/pull they are subscribed and will receive notifications for every reply.

@JoshDreamland I'm busy with freelance work right now but I'd love to get some assistance on this if I can't figure it out on my own, I've tried show_message(execute_shell_for_output("echo 1")) and it always shows some random foreign characters, I think because I am doing the wide char version of popen but not the other functions such as fread but I can't seem to find the wide char versions of the other functions, is the biggest issue. I really need this to be cross-platform for something I'm working on. I need UTF-8 support.

[JoshDreamland]

From the Microsoft docs:

_wpopen is a wide-character version of _popen; the path argument to _wpopen is a wide-character string. _wpopen and _popen behave identically otherwise.

[time-killer-games]

Then that's really odd, I wonder why it isn't working then.

[time-killer-games]

@JoshDreamland to clarify what isn't working, the command argument works and it executes stuff, but the output doesn't and it returns random crap characters. While stuff is executing and you try to click on or interact with the game window too much, the game will segfault.

Microsoft seems to be bad at naming things... anyway, thank you, Sam; this looks great!
