+@cindex file names, invalid characters on MS-Windows
+  Unlike Unix, MS-Windows file systems restrict the set of characters

+
+@itemize @bullet
+@item
+Shell redirection symbols @samp{<}, @samp{>}, and @samp{|}.
+
+@item
+Colon @samp{:} (except after the drive letter).

+Forward slash @samp{/} and backslash @samp{\} (except as directory
+separators).

+Wildcard characters @samp{*} and @samp{?}.

+names when you want to use the corresponding character device.
