Ruby error UTF-8 to ASCII

问题:

I have a Ruby 1.9.2 install on Centos 5.5. Every time I install a gem, I get the error

ERROR:  While generating documentation for (gem)
... MESSAGE:   U+2018 from UTF-8 to US-ASCII
... RDOC args: lib History.txt README.txt

The gem still installs ok, but there are certain things I can't do. Like use SproutCore, for example. I get this little gem (pun intended).

sc-init xxxx
 ~ Created directory at xxxx
FATAL ~ invalid byte sequence in US-ASCII 

Anyone have any idea what's going on, and how to remedy it? Google isn't much help on this one.

RDoc updated last week, and was supposed to help fix encoding problems.

Try gem update rdoc and see if that helps.
