The C<use bytes> pragma disables character semantics for the rest of the
lexical scope in which it appears. C<no bytes> can be used to reverse

as a series of bytes.
As an example, when Perl sees C<$x = chr(400)>, it encodes the character
-in UTF8 and stores it in $x. Then it is marked as character data, so,
+in UTF-8 and stores it in $x. Then it is marked as character data, so,
for instance, C<length $x> returns C<1>. However, in the scope of the
C<bytes> pragma, $x is treated as a series of bytes - the bytes that make
up the UTF8 encoding - and C<length $x> returns C<2>:
