StringToASCIIArray() with UTF-8 encoding gives wrong result

Local $str = BinaryToString(Binary(0xB2CEB1CE), 4)		; converting 2 utf-8 symbols (CE B1 - alpha, CE B2 - beta) to string
MsgBox(1, "utf-8 string", $str)					; test if symbols are properly converted
Local $arr = StringToASCIIArray($str, 0, Default, 2)		; convert string to array of utf-8 charcodes

$str = "["
Local $i

For $i = 0 To UBound($arr) - 1
	$str &= StringFormat("0x%X, ", $arr[$i])		; get array content. expecting [0x0000B1CE, 0x0000B2CE], right?
MsgBox(1, "utf-8 array", StringTrimRight($str, 2) & "]")	; see [0xFFFFFFB1, 0xFFFFFFCE]

Environment = under WIN_XP/Service Pack 2 X86

This line of code:

Local $str = BinaryToString(Binary(0xB2CEB1CE), 4)

After that call you are done with UTF-8. The variable $str now UNICODE. The problem is you are mangling the data in the call to StringToASCIIArray() because you lie to it and tell it the string is UTF-8 when in reality no it's not. However, it does what you tell it to and returns garbage as a result. I hope I don't need to explain what the fix is.

This is not a bug.
