Yes, I have fixed that now.

No, we can't force an output charset on people since it would end up
breaking a lot of sites.

PHP 5.3's determine_charset behaves exactly like 5.4's. In 5.3 we have:
if (charset_hint == NULL)
return cs_8859_1;
and in 5.4 we have:
if (charset_hint == NULL)
return cs_utf_8;
So there is no difference in their guessing when there is no hint, the
only difference is that in 5.4 we choose utf8 and in 5.3 we choose
8859-1 in that case.
