I'm using the PEAR Crypt_Blowfish module. When I decrypt the encrypted string the result is the original plus some '\ufffd' bytes. How can I get rid of those extra bytes? I've tried both trim($x,'\ufffd') and trim($x,utf8_decode('\ufffd')).

trim() is meant to remove chars from the beginning and ending of a string. http://us2.php.net/str_replace is meant to remove a set of chars from a string. Anywhere within the string.

But it *is* a single char that I'm wanting to remove (multiple times). Perhaps you are confusing a char with a byte?

Nope, not confused, but I ASSUMED that maybe the chars were not at the beginning or ending of the string, but somewhere in the middle. ( you didn't say where the chars were )

Yes, I did. "the original *plus* some '\ufffd' bytes" clearly means that they were added at the end.

Well, IMHO, that does not "clearly mean" at the end. *plus* does not imply, to me at least, that whatever the plus is, is appended to the end.

And since you were using trim(), that you were using the wrong function. Which only works on the beginning and ending of a string.

I wanted to remove the characters that were added at the *end* of the string.

obviously...?
