Game log isn't encoded with UTF-8

Version of Prism Launcher

Version of Qt

Description of bug

When non english characters (in this case, Russian) characters appear in the log (the log within Prism), they appear encoded incorrectly.

This is copied and pasted from the log

[14:52:54] [Render thread/INFO]: [CHAT] игрока, пригла�ившего Ва� на �ервер.
[14:52:54] [Render thread/INFO]: [CHAT] 
[14:52:54] [Render thread/INFO]: [CHAT] �аграда: ᴇ�ᴇʀᴀʟᴅ на 3 дн� (Вам и Пригла�ившему)
[14:52:54] [Render thread/INFO]: [CHAT] Е�ли у Ва� уже е�ть ᴇ�ᴇʀᴀʟᴅ, тогда

Steps to reproduce

1. Copy and paste something in russian in chat
2. Open Prism log
3. See how the chat message appears incorrectly

Suspected cause

I suspect the log isn't using UTF-8 like it should be.

This issue is unique

• I have searched the issue tracker and did not find an issue describing my bug.

This may be due to how your locale is set up, as this works as intended for me on linux.
Make sure your windows locale is set correctly(no I have no idea how to do stuff on windows so search for it on google).

I've looked it up, and it says the locale for Windows is only used when the application doesn't support unicode. This makes me think that there is some program field somewhere that says whether the program supports it or not.

My current locale was set to English US, which is fine. The locales available are only regional locales (every language with variants for location).

Prism uses that locale to decode the std output of Minecraft: https://github.com/PrismLauncher/PrismLauncher/blob/develop/launcher/LoggedProcess.h#L84
try adding Russian or something there
