If the character encoding used by an external program doesn't match the encoding stored in [console]::OutputEncoding, PowerShell will misinterpret the program's output, if captured or redirected.

Assuming that MediaInfo outputs UTF-16LE-encoded text, run the following beforehand (and restore the original encoding afterwards, if needed):

[console]::OutputEncoding = [System.Text.UnicodeEncoding]::new()

Generally, [console]::OutputEncoding still defaults to the active OEM code page on Windows, unfortunately - see #7233; on Unix-like platforms, it is sensibly UTF-8.

Thx this sloves the problem for me.
