program, these will typically occur directly within the literal strings
as UTF-8 characters, but you can also specify a particular character
with an extension of the C<\x> notation. UTF-8 characters are
-specified by putting the hexidecimal code within curlies after the

character in the Latin-1 range (128..255) should be written C<\x{ab}>
rather than C<\xab>, since the former will turn into a two-byte UTF-8
code, while the latter will continue to be interpreted as generating a
-8-bit byte rather than a character. In fact, if -w is turned on, it will

produce a warning that you might be generating invalid UTF-8.
