ODE TO A SHIPPING LABEL
Once there was a little o,
with an accent on top like só.
It started out as UTF8,
(universal since ’98),
but the program only knew latin1,
and changed little ó to “Ä³” for fun.
A second program saw the “Ä³”
and said “I know HTML entity!”
So “Ä³” was smartened to “&ATILDE;&SUP3;”
and passed on through happily.
Another program saw the tangle
(more precisely, ampersands to mangle)
and thus the humble “&TILDE;&SUP3;”
