Sieve doesn´t filter emails with words with accents

[Sebas PRE]

Yes, the strings of my sieve script are in UTF-8, this is my script:

require "fileinto";

# Leido
if header :comparator "i;ascii-casemap" :contains "Subject" "Leído"  {
    fileinto "TESTBOX";
}

but it doesn´t work.


Greetings...

Sebastián Calero.
