[APP BUG]: "Directory to Install Game Path doesn't handle characters with accents

[Exo61]

Describe the Bug

When installing ShadPS4 into a directory or path with a character containing an accent (like "É"), the path has to be re-added every time ShadPS4 is being launched.

The main reason is that it replaces the character with an accent by multiple symbols, corrupting the path and therefore not listing games anymore.

Here is a screenshot: https://ibb.co/27x4Stw4

Can you fix this issue?

Thank you

Reproduction Steps

1. Add a Directory to Install Game Path containing a symbol with an accent, like "É"
2. Close ShadPS4
3. Re-open ShadPS4
4. Check the the Directory to Install Game Path again and see the symbols
5. Games are not listed anymore until re-adding the path with the right character again

Expected Behavior

Directory to Install Game Path remains the same everytime ShadPS4 is open, no matter the name of the folders

Specify OS Version

Windows 11

Hello,

I am currently investigating the cause of the problem and can already conclude that it is not due to the saving of the path in the configuration file. In the config.toml file, the path is correctly stored with the accents. Therefore, it is probably the in-memory loading of the string that is causing the issue.

After reopen ShadPS4 :

The string in config.toml file :

If I use a debugger, this is what I get: the string loaded in memory doesn't handle the accents. It would be interesting to see if it's the same on Linux. (src/common/config.cpp)
