I don't have a copy of ISO standard, but Roman Czyborra states
"... the positions 128 to 159 hold some less used control characters:
the so-called C1 set from ISO 6429."
(http://czyborra.com/charsets/iso8859.html)

Also, Unicode mapping table
(http://www.unicode.org/Public/MAPPINGS/ISO8859/8859-1.TXT) assigns
0x80-0x9f to the corresponding Unicode control characters. So my
understanding is that there is no unassigned code point in ISO-8859-1
code space.

I agree with you that if the conversion fails Java returns REPLACEMENT
CHARACTER rather than a null string.
