+fnameescape({string})					*fnameescape()*
+		Escape {string} for use as file name command argument.  All
+		characters that have a special meaning, such as '%' and '|'
+		are escaped with a backslash.
+		For most systems the characters escaped are "".  For systems
+		where a backslash appears in a filename, it depends on the
+		value of 'isfname'.
+		Example: >
+			:let fname = 'some str%nge|name'
+			:exe "edit " . fnameescape(fname)
+<		results in executing: >
+			edit some\ str\%nge\|name
