[BUG] opening files with special characters make Sioyek crash

[Kim-Vallee]

It's just a small bug that makes Sioyek crash if a file with special characters is open and one tries to open another one.

The terminal shows the following error :

terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error'
  what():  filesystem error: Cannot convert character sequence: Invalid or incomplete multibyte or wide character
Aborted (core dumped)

How to reproduce:

1. Prepare two PDFs A.pdf and B.pdf
2. Rename A.pdf with the name í.pdf
3. Open í.pdf
4. Through a new call of Sioyek (not opening through the already existing window) try to open B.pdf
5. Sioyek should have simply closed

I'm happy to provide more information if needed. Thanks for the project, it's awesome !

Can't reproduce this issue on windows. What platform are you using and which sioyek version (e.g. did you download it from a package manager?)

I have it on Linux, AppImage version (last one I got it from the website).
