[Dovecot] Sieve and locale (Japanese), string length

[Jorgen Lundman]

Damn I apologise for the noise now, but I did manage to run into one problem:

Subject: 日本語らららららららららららららららららららららららららららららららら 
ららららららららららららららららららららら

Subject: =?UTF-8?B?5pel5pys6Kqe44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ?=
  =?UTF-8?B?44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ?=
  =?UTF-8?B?44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ?=
  =?UTF-8?B?44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ44KJ?=
Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: 7bit

Testing against:

if header :contains "Subject" "らららららららららららららららら" {
   fileinto "nihongo";
}

=> OK



if header :contains "Subject" "ららららららららららららららららら" {
   fileinto "nihongo";
}

=> NG


So it seems the longest word test is 16 UTF8 chars (or 48 bytes?). So as long as 
we use small words, it should be ok.

Out of curiousity, can we increase this limit?
