[Tutor] sig no matter what

[Jim Mooney]

It looks like sig works for any dash, underline combination, and is ignored
if there is no BOM:

>>> farf = bytes('many moons ago I sat on a rock', encoding='utf8')
>>> farf
b'many moons ago I sat on a rock'
>>> str(farf, encoding="utf_8_sig")
'many moons ago I sat on a rock'
>>> str(farf, encoding="utf-8-sig")
'many moons ago I sat on a rock'
>>> str(farf, encoding="utf_8-sig")
'many moons ago I sat on a rock'
>>> str(farf, encoding="utf-8_sig")
'many moons ago I sat on a rock'

the next great app, with No Programming!" There's always a sucker for
get-rich-quick schemes.
