Thanks, but I'm well aware of the magic comments.
You're missing the point(s):

$ rvm use 1.9.2
$ ruby -e 'p __ENCODING__'
#<Encoding:UTF-8>

so the default encoding is UTF-8. Why does a UTF-8 file fail to be parsed as UTF-8 then?
(Answer: because Ruby has a schizophrenia about its default encoding, and defaults to US-ASCII
for files).

Next,

$ ruby -h

lists 23 lines of options, but not -K, which is the one that fixes the above problem. Why?
(Answer: because someone made arbitrary decisions about which options need -h help,
or made changes in options without bothering to cross-check the help. Arbitrary, or careless,
you choose. Either way it should be fixed.)
