Another Email Problem

[compressor stall]

Of the maybe 50 people I email, 3 receive my text as nothing but "ÿþ". Just those 2 characters and nothing more.

I am using Outlook Express on a Toshiba Laptop running Win98 through a hotmail account.

There seems to be no pattern at all with the recipients' ISPs, and others with the same ISP receive my emails just fine.

Any ideas?

Cheers
