It can't be done (as far as I know) without hacking the Perl source.

You can, however, create a character class that contains both \s and your "extra" character - [\s\0xA0]. You can even create a variable that contains your character class and use that in your regexes.

my $ws = '[\s\0xA0]'; # white space

$data =~ s/^$ws+|$ws+$//g;
