Paths with characters outside ASCII gives error FS2302 (Windows)

[Whil-]

Description

When I execute code inside fsharp-files (using C-c C-e for example), and the path to the file contains non-ASCII characters I get the FS2302-error:

`
#silentCd @"c:/temp/Non-ASCII_Ö/";;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

stdin(1,1): error FS2302: Directory 'c:/temp/Non-ASCII_Ö/' doesn't exist
`

Repro steps

1. Create folder with for example ö in the name.
2. Add a fsharp-script inside the folder, run the code.

Expected behavior

No error.

Actual behavior

Error FS2302

Known workarounds

Rename folder so that it doesn't contain non-ASCII characters.

I can confirm this issue. Interestingly fsi.exe can handle non-ascii paths in a shell/cmd buffer but it fails when using a comint buffer.

@Whil- Should be fixed by #178 in master (no melpa release yet):

Could you please test/confirm?

Thanks!

Thanks, I'll test it when the new melpa-package is out.
