Direct redirection of a custom object ([pscustomobject] instance) to a file with ">" produces no output. #4812
Description
Even though > is not an actual alias of Out-File, it usually is an effective alias; the two generally behave the same.
However, when outputting a [pscustomobject] instance, > apparently produces an empty file (the file contains only the UTF16-LE BOM and a newline):
Steps to reproduce
# Use Out-File explicitly.
[pscustomobject] @{ one = 1 } | Out-File tmp.txt; Get-Content tmp.txt
'---'
# Use > instead of Out-File, which should produce the same result.
[pscustomobject] @{ one = 1 } > tmp.txt; Get-Content tmp.txtExpected behavior

I.e., using > instead of Out-File resulted in an empty file (just the UTF16-LE BOM and a newline).
