Hello everybody, a linguist in pain over here.

I am trying to clean up a corpus of utf8 texts which contain mainly Russian Cyrillic by removing all the Latin text that's in them. Of course, I need to keep the punctuation, spaces etc.

Unicode seems to be doing fine, because when I use: print s/[\P{InCyrillic}]//g; I really get only Cyrillic strings piled up against each other, no punctuation, no spaces and no latin letters. So far, so good.

But when I try to create my own character definition in a subroutine, things stop working as expected. 

#! usr/local/perl 
use utf8;

sub InRussian{
return <<'END';
    +utf8::Cyrillic
    +utf8::Mark
    +utf8::Number
    +utf8::Punctuation
END
}

print s/[\P{InRussian}]//g;

I only get digits without spaces, which makes no sense to me.

Even when my subroutine contains only +utf8::Cyrillic-- the result is digits and not the same as print s/[\P{InCyrillic}]//g;

I'm calling the perl script from bash with -CS -p. I'm using perl 5.8.6 on Mac OS X. Any help would be greatly appreciated.

Mike
