RTFM:
"This function decodes data , assumed to be UTF-8 encoded, to ISO-8859-
1."

chr(0xf0).chr(0xc0).chr(0xc0).chr(0xa7)

is not a valid utf8 data.

We know it is not, but the function only works on proper UTF-8 like is documented. So there is no bug here, the bug is on your code calling this function. You can't require functions to work like they're not meant to work—but that's what you're asking here.
