Even though you entered a NNBSP on the command line, your program doesn't contain a NNBSP. (And I'm not referring to the appearance of  . That's due to a PerlMonks limitation.)

By default, Perl programs are expected to be encoded using ASCII. NNBSP isn't found in the ASCII character set, so your program can't possibly include a NNBSP.

Assuming a UTF-8 terminal, what you actually provided Perl is equivalent to "...\xE2\x80\xAF...". But a string containing a NNBSP would be "...\x{202F}...".

You can tell Perl that the program is encoded using UTF-8 by adding use utf8;.
