I think you mean 11.9.0 and not 11.9.4?
Anyway: I'm avoiding non-7-bit-ASCII characters in paths or file names, as it only causes troubles with the GNU toolchain, e.g. include paths and other path or file related things.
What you could use instead on windows: use the 'subst' command to create a virtual drive letter to your projects, e.g.
subst p: C:\User\Milosz\myProjects
and then use the P:\ driver for it.
