Actually we need a function doing "binary chr" - chr() in PHP 6 takes a codepoint not the byte value, so  (binary)chr($c) will give the wrong result.

$b = sprintf("%c%c%c", 255, 254, 253);

should work, but having a simple function might still be helpful

hmmmmmmm....... try code above.

b1.dat consists utf-8 data
b2.dat consists binary chars 0 - 255 step 1, file length is correct - 256B & chars are correct...

 if(substr(phpversion(),0,1)!='6'){trigger_error('only PHP 6',E_USER_ERROR);}

// unicode.semantics = off
// unicode.runtime_encoding = iso-8859-1
// unicode.script_encoding = utf-8
// unicode.output_encoding = utf-8
// unicode.from_error_mode = U_INVALID_SUBSTITUTE
// unicode.from_error_subst_char = 3f
