gem fails to install with 'invalid byte sequence in US-ASCII'

I'm having an issue installing the latest version of the gem (1.11.3.2). Here's the output with backtrace:

ubuntu@machine:~$ sudo gem install rvm --backtrace

I am running stock 1.9.2 on ubuntu 11.10 oneiric.

ubuntu@machine:~$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
ubuntu@machine:~$ gem -v
1.3.7

I can install version 1.11.3, but not 1.11.3.1 or 1.11.3.2:

ubuntu@machine:~$ sudo gem install rvm -v=1.11.3.1
ERROR:  While executing gem ... (ArgumentError)
    invalid byte sequence in US-ASCII
ubuntu@machine178:~$ sudo gem install rvm -v=1.11.3
***********************************************************************************
...
Successfully installed rvm-1.11.3

Installing RDoc documentation for rvm-1.11.3...

I am, however, able to install both of these troublesome versions without issue on my local machine that is running 1.9.3-p0 installed via rvm.
