Gibberish returned from forms

Hi - I don't know whether I'm looking in the right place for information, but I figured it couldn't hurt. We have our website hosted at a place that uses PHP. We have several forms that users submit information to us with. Just lately the email that we receive is completely unreadable. Here's a sample (note that the first line is OK, and usually is): Gwen Fremonti at Yew Creek Institute submitted the followEën®sÚ¶h²Ùs²×«s?n-ë ®<©r?Ozˁâ5q LDOD""t£¼Ý4ÓM7ïÙñz{^®sâ±é¨vén² èº-(Ts«S§jP+®+Ú.8¦{mLk-´Ómzß~9ÓͼQ0. ± Áã¡nÓPÓAin ifomaio: Prdut am: esryt/DI rouc VrsonNube: .#.# omutr peatngSyte: C:Widos T/00 ririy:48hors Eai PF:Ye pdtesotwre Ys Prvie emorryliene:Ye eranntliene:#### Sppy rouc mdi: C:Elctonc Aditonl nfrmtin:May,I m esin tisfom.I no tisisal gbbrih,bu cul yu leselok t hevCrdatacedtoth milmesae ndtel e hehe al heinoratonapeas o e hee,an weterth ifomaio i te ots ied ppar t b tunatd?Thnk, we.

Does anyone have any idea what could be causing this, or whether it's even related to the mail script?
