Research direction
No source file, test, or entry point is identified in the issue. Start by reproducing the Cyrillic preview problem with an Outlook-sent message, compare it with a Thunderbird-sent message, and trace where the message body becomes question marks. Done means the first preview line remains readable for both sending paths, with a regression test covering the affected encoding.
