Um...two guesses.

  1. You are using negation \P{} and NOT(+A +B) doesn't mean what you intend. Eg. 'not in A and not in B'?

    Maybe you need (something like): 

    sub NotInRussian{
    return <<'END'; 
!utf8::Cyrillic
!utf8::Punctuation 
END
}
...
s/\p{NotInRussian}//g

  2. It might have something to do with this from the POD?
    A final note on the user-defined property tests and mappings: they will be used only if the scalar has been marked as having Unicode characters. Old byte-style strings will not be affected.

    Does your editor produce unicode source files? Will Perl promote ASCII source to unicode?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
