DESCRIPTION

16       You can't just rely on "" to be a valid empty string  in  any  encoding
17       format.  This  global buffer contains a number of consecutive zeros, so
18       it will be a valid empty string no matter whether the program  is  run‐
19       ning in ASCII, Unicode, or UTF-8 mode.
