+$PSVersionTable.PSEdition
+
+If 'shell' includes "powershell" in the filename at startup then VIM sets

+'shellpipe'	>%s 2>&1
+'shellredir'	>%s 2>&1
+
+If you find that PowerShell commands are taking a long time to run then try
+with "-NoProfile" at the beginning of the 'shellcmdflag'.  Note this will
+prevent any PowerShell environment setup by the profile from taking place.
+
+If you have problems running PowerShell scripts through the 'shell' then try

+
+The 'shellpipe' and 'shellredir' option values re-encode the UTF-16le output
+from PowerShell Desktop to your currently configured console codepage.  The
+output can be forced into a different encoding by changing "default" to one of
+the following:
+
+	unicode		 - UTF-16le (default output from PowerShell 5.1)
+	bigendianunicode - UTF-16
+	utf8		 - UTF-8
+	utf7		 - UTF-7 (no BOM)
+	utf32		 - UTF-32
+	ascii		 - 7-bit ASCII character set
+	default		 - System's active code page (typically ANSI)
+	oem		 - System's current OEM code page
+
+Note The abovce multi-byte Unicode encodings include a leading BOM unless
+otherwise indicated.
+
+By default PowerShell Core's output is UTF-8 encoded without a BOM.  If you
+want to force the output of PowerShell Core into a different encoding then set
+'shellredir' and 'shellpipe' to "2>&1 | Out-File -Encoding encoding" where
+encoding is one of the following:
+
+	ascii		 - 7-bit ASCII character set
+	bigendianunicode - UTF-16be
