The distinction between the Unicode and ISO versions of UTF-8 is pretty
irrelevant. ISO UTF-8 allows a maximum of 6 octets because it is designed
to accommodate a larger codespace than Unicode, but the portion of the
codespace beyond U+10FFFF is now permanently reserved. For all practical
purposes, the usable ISO codespace is the same as that for Unicode, and
thus the usable ISO UTF-8 sequences are at most 4.
