[imapfilter-devel] i18n and difference bitween match_subject() and contain_subject()

[Alexander Polyakhov]

Hi.
I decide to manipulate with message which subject is exactly "Ответ на 
ваш комментарий на example.com"
My rule is invalid in imapfilter decision. It`s here:
result = server.username.INBOX:contain_subject('Ответ на ваш комментарий 
на example.com')

I`ve modified it. Now it works:
result = server.username.INBOX:match_subject('Ответ на ваш комментарий 
на example.com')

Why does the "contain" method fails?
