Game does start under linux with save path: "~/Łsaves/"
With only one error:
[INFO]: Error on parsing profile: No such node (Setup.Resolution)
OpenGL 2.1 Ubuntu 14.04.1 LTS

It works correctly for me on Linux too

krzys_h@krzysh-laptop:~/Pulpit/colobot/build$ ./colobot -savedir ./saves_Ł

No errors about setting save path or mounting it.

I've also tried to add more Polish characters, but it still works correctly:
[INFO]: Save path: ./saves_ąęśćżń

I'll test that on Windows later.

The windows file system uses UTF-16 for such characters. To edit a file with polish name, convert your UTF-8 string to UTF-16, then create it with the UTF-16 name. Maybe you can do it using "codecvt_utf8_utf16".
Sorry, cant test it myself because i have no Windows at home
UPD:
I also saw same problem before, on Jedi Academy sources...

Looks like the -savedir argument is encoded as Windows-1250
