Hi Aasianov,
try retrieving the SmartObject field containing the attachment as an InfoPath 'attachment' control. If this works, then you can use some code to retrieve the unicode attachment and display it in another control type, such as image or document.... I believe this is possible.
See: http://blog.mgallen.com/?p=94
for code to get the filename out of a unicode attachment.
