(Menu) [Windows] Garbled filenames with Chinese characters

Description

Select a game with a Chinese filename in a playlist, select "Add to Favorites", and then run the game in the "Favorites" list. The prompt "File could not be loaded from the playlist" appears. Select "Information" in the "Ouick Menu", and you can see that "File path" has garbled characters.

Expected behavior

Games with Chinese filename can be added to favorites and run successfully.

Actual behavior

Games with Chinese filename can be successfully added to the collection, but cannot be run because "File path" becomes garbled. Prompt "File could not be loaded from the playlist".

Steps to reproduce the bug

1. I have a playlist called "N64", and there is an N64 game called "塞尔达传说-时之笛(汉化版).zip"("The Legend of Zelda - Ocarina of Time (Chinese Version)") in the playlist.
2. Select this game and then select "Run", the game can run successfully.
3. Exit the game and select "Add to Favorites" in the "Ouick Menu".
4. Navigate to the "Favorites" list, you can find this game, but it won't run, prompt "File could not be loaded from the playlist"
5. Select the game in the "Favorites" list, then select "Information" in the "Ouick Menu", and find that "File path" becomes "塞尔达传�?时之�?汉化�? .zip"。

Game in the "N64" playlist:

Name: 塞尔达传说-时之笛(汉化版)
File path: D:\RetroArch\Roms\N64\塞尔达传说-时之笛(汉化版).zip

Game in the "Favourite":

Name: 塞尔达传说-时之笛(汉化版)
File path: D:\RetroArch\Roms\N64\塞尔达传�?时之�?汉化�? .zip

The Chinese "Name" is no problem, but the "File path" is garbled.

Bisect Results

During the process of adding from playlist to Favourite, did the file path undergo any conversion?
