Parallel with Asian characters

[1480c1]

parallel seems not to be able to understand Windows directory structure, and thus when I put {/} for basename, it just outputs the whole entire line and when I use {.} it outputs the whole entire line, minus the file's extension. This is under Powershell in Windows 10, not only that, it seems to not be able to understand Asian characters.

When I use ls -Recurse -file -Path '*.m4a' | select -ExpandProperty FullName | parallel 'echo {.}'
it will not understand at all
