pl/pgsql and national characters

Hello All,

I have a following problem. I have a tables and fields whith names,
consisting of cyrillic characters and getting an error. When I am
doing the same things but with only english characters, everything ok.
All other things works properly, only pl/pgsql functions. Does anybody
knows how to treat this?
Here is an example:

create function round_mark() returns opaque as '
begin
NEW."<cyrillic characters>" := 1;
return NEW;
end;
' LANGUAGE 'plpgsql';
CREATE

CREATE TRIGGER marks_round_marks BEFORE INSERT OR UPDATE ON "rr"
FOR EACH ROW EXECUTE PROCEDURE round_mark();
CREATE

UPDATE "rr" SET "<cyrillic characters>"=1 WHERE "<cyrillic characters>" = 1;
NOTICE: plpgsql: ERROR during compile of round_mark near line 1
ERROR: unterminated "
