Storing encrypted data?

Hi, <br /><br /> Does anyone have experience with storing encrypted data into pgSQL? I have a pgSQL database which
usesUTF8 encoding. I am encrypting plain text in my (GUI) application and sending it to a field (with data type 'text')
inmy database. <br /><br /> I get an error back saying "invalid byte sequence for encoding UTF8; oxd733"<br /><br /> I
amusing blowfish at 128bit to encrypt the string.<br /><br /> The encrypted string comes out looking like this<br /><br
/><fontface="Arial" size="-1">Salted__ë±9r™LZPÃOG¤u–¨ékTz~6Ëpi™|O +LÏ°‹r°ô9•mµ�á%€©õP{:‚Àªd<br />

<br/><br /> The statement has been working, until I got to a string that generated the above encrypted data, then it
broke.<br/><br /> Alternatively, can anyone suggest an encryption algorithm that will only return characters that are
validUTF8 encoded?<br /><br /> Thanks in advance<br /><br /> John T<br /><br /><br />
