of this list, only UTF-EBCDIC is a viable encoding form.
the others are either deprecated, never made it beyond draft, or are unofficial discussion pieces that never made it anywhere (i proposed one of them :-).
if you detect all the big- and little-endian boms for the standard forms
utf-8, utf-16, utf-32, scsu, utf-ebcdic
then you will be a hero. any of them may come with a bom depending on protocol and os.
