Hello, everyone!

I have some stranhge problem - hope smb will help me solve them:

I keep of tracking Drupal project since last 3.x version for making my own
site - that's was all right, but when I take last 4.x version (from site) -
I found the following problem:
When I try to add a new story (in my native language - russian, codepage -
cp1251 -- windows russian codepage), and press "Preview" and then "Submit"
button - I get smth really strange in body & teaser of the message, but not
in the title!
The same is right for pool module.

So, summarising the description of the problem I can say, that there is a
problem in working with codepage in body of the nodes, but there is no such
problem with the title. That made normal postings impossible in languages
different from english.
I looked through the sources, but the structure of the code was changed
since V3 & I found nothing about this (there was no such problem in last 3.x
version).

Is it a bug, feature, or just my misunderstanding of smth?

Hope you will help me, because I can't find any desision for that problem
for about week... =\

/Alexandre.
