Trying to block a type of email w/ Charset font/text (help please)

[CorCentral]

I'm recieving these VERY annoying emails with "Charset 1251" font & I'm trying to block them but do not have this type of text within Win2000 .
Here is what the text looks like ....... Ïðåäëàãàåì áûñòðî âûó÷èòü

Is there a way to download this text ?

Thanks .
