(F) Encountered an ill-formed \s-1UTF\-8\s0 octet sequence. <%s> contains a hexadecimal 
representation of the maximal subpart of the ill-formed subsequence.
.IP "Can't interchange noncharacter code point U+%.4X" 4
.IX Item "Can't interchange noncharacter code point U+%.4X"
(F) Noncharacters is permanently reserved for internal use and that should 
never be interchanged. Noncharacters consist of the values U+nFFFE and U+nFFFF 
(where n is from 0 to 10^16) and the values U+FDD0..U+FDEF.
