wsl --import/--export does not handle paths with spaces or quoted paths correctly

[0xbadfca11]

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.18362.1]

• What you're doing and what's happening: (Copy&paste the full set of specific command-line steps necessary to reproduce the behavior, and their output. Include screen shots if that helps demonstrate the problem.)

C:\Users\JohnDoe> wsl --export Ubuntu "Ubuntu.tar"
The filename, directory name, or volume label syntax is incorrect.

C:\Users\JohnDoe> wsl --import Ubuntwo C:\Ubuntu "C:\Program Files\WindowsApps\CanonicalGroupLimited.UbuntuonWindows_1804.2018.817.0_x64__79rhkp1fndgsc\install.tar.gz"
The filename, directory name, or volume label syntax is incorrect.

• What's wrong / what should be happening instead:
  Both file paths should be treated correctly.

• Workaround
  Use stdin/stdout.

Good find, I'll sort this out.

Fixed in Windows Insider Build 18890

My Windows version is 10.0.18362.476.

I have the same problem - I cannot even export.

wsl -l shows:

Legacy (Default)

Trying to export it:

wsl --export "Legacy (Default)" ubuntu.tar

Shows me the exact same error as above:

The filename, directory name, or volume label syntax is incorrect.

I tried to pipe it directly to file like this:

wsl --export "Legacy (Default)" > ubuntu.tar

ubuntu.tar will include the exact same error message.

I suspect that the problem is with the distribution name (Legacy (Default)) itself. Can I rename distribution somehow to test it out? How would I solve this problem with a workaround?

Forgot to mention - I tried different working directories without having any positive effect.

After upgrading Windows to 10.0.19033.1 via Insider Program I managed to export like this:

wsl --export "Legacy" ubuntu.tar

Note, that I had to omit " (Default)". I also tried that with the previous version and got an error message that Distribution with the name "Legacy" was not found.
