Crash when opening a directory containing a file with a weird character in its extension

[Sean]

What I've done to isolate the issue:

• I added a file named sequence.🗿 to another folder | ERROR
• I added a png to another folder, then appended 🗿 to the file extension. I then opened the new folder. | ERROR
• I made the file with 🗿 in the filename instead of the extension. | NO ERROR

The exception in question:
Unhandled exception at 0x00007FF83338CF19 in program.exe: Microsoft C++ exception: std::system_error at memory location 0x000000B6F7F0CC38.

[External Code]	

Looking at the call stack and using context, the problem most likely lies in ImGui::FileBrowser::IsExtensionMatched()

Looks like this is caused by windows error 1113 (no mapping for the unicode character exists in the target multi-byte code page) in the implementation of std::filesystem::path::string. I will fix it soon.

Please try the new version

Works fine now!
