Vagrant doesn't work on Windows if user has special characters in the username

[zanmoskotevc]

Vagrant version

Vagrant 2.2.7

Host operating system

Windows 10 Pro N

Expected behavior

Vagrant should work with special characters in Windows username.

Actual behavior

It doesn't. It throws this:

C:/HashiCorp/Vagrant/embedded/gems/2.2.7/gems/vagrant-2.2.7/lib/vagrant/environment.rb:193:in `encode': U+017D to IBM437 in conversion from Windows-1252 to UTF-8 to IBM437 (Encoding::UndefinedConversionError)

Steps to reproduce

1. Create a Windows user with special characters in name (ščžäöü for example, or any special character...)
2. Try running any vagrant command
3. Get the error

References

Are there any other GitHub issues (open or closed) that should be linked here?
For example:

• VAGRANT_HOME special characters don't work #2113 (from 2013)
• io.rb:32:in `encode': "\xE7" from IBM857 to UTF-8 (Encoding::UndefinedConversionError) #9368 (from 2018)

This is fixable using a custom path (setx VAGRANT_HOME), but I don't think that should be necessary.

[geqo]

Still not working.
