If the whole text consists of "valid bytes" according to the definition
of Shift-JIS, the conversion from sjis to utf-8 will not "fail", but if
the text was written using a different encoding, the result will
probably not "make sense". In that case you will get garbled text.
"Failing", from the point of view of the iconv routine, means "finding a
byte sequence which is invalid for the 'from' encoding at the position
where that sequence was encountered".
Similarly, conversion from Latin1 to UTF-8 will never fail, because any
byte is "valid" in Latin1; but if the text was originally written in
some non-Latin alphabet (using an encoding appropriate for that
alphabet), the result will not make sense.
