Outlook mail encoding

[nastya]

Hi,
I'm writing a com adding to MS Outlook.
How can i get encoding, that outlook automatically selects for email sending?

If the message contains these characters: Outlook selects this encoding:
English (ASCII) text (A-Z, a-z) US-ASCII
German (Latin 1) text (A-Z, a-z and Umlauts) Western European (ISO)
Greek text (A-Z, a-z and Greek characters) Greek (ISO)
Japanese text (A-Z, a-z, Hiragana, Katakana, Kanji) Japanese (JIS)
Multilingual text (different scripts) Unicode® (UTF-8)

Where can i find it?

Thanks,
Anastasia

I'd like to focus my question ...
How can i get/set body or subject from/to MailItem where they are not in english?
By now i get "???????" or other simbols, that have nothing to do with real body or subject.
Thanks,
Anastasia
