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 " \t\n*?[{`$\%#'"|!<". For systems where a backslash appears in a filename, it depends on the value of 'isfname'. A leading '+' and '>' is also escaped (special after |:edit| and |:write|). And a "-" by itself (special after |:cd|). Example: :let fname = '+some str%nge|name' :exe "edit " . fnameescape(fname) results in executing: edit +some\ str%nge|name Can also be used as a |method|: GetName()->fnameescape()
