Off the top of my head, every "token" of text in Perl is either:
* an operator: +, *, =~, s///, ..
* a built-in function: chomp(), map(), grep()
* an imported function or method from a module: $cgi->param()
* a user defined subroutine or method: do_stuff_with()
* a string: "including" qw{ things like }, qq[ this ], 'or', "this"
* a bareword: FILEHANDLE, etc
I may have missed a class or two, but that's most of them.

A non- operator / function / method / subroutine / string that includes
one or more UTF8 characters.

Well, if used exactly as you have it there, it's a string, because it's
wrapped in double quotes. If you just had
\x69\x22
by itself, then yes, it would be a bareword.
