   Found a solution! The problem is rdoc.
   let's take a look at how I did it:

   C:\Windows\system32>ruby -v

   ruby 1.9.2p136 (2010-12-25) [i386-mingw32]

   C:\Windows\system32>gem update

   Updating installed gems
   Updating bundler
   Fetching: bundler-1.0.10.gem (100%)
   Successfully installed bundler-1.0.10
   Updating mail
   Fetching: mail-2.2.15.gem (100%)
   Successfully installed mail-2.2.15
   Updating rdoc
   Fetching: rdoc-3.5.1.gem (100%)
   RDoc 2.5 did not save method parameters, so you should upgrade your rdoc-dat
   gem to a version >= 2.5.3.

   To have ri data for core and stdlib you'll need to:

   gem install rdoc-data

   then run:

   rdoc-data --install

   To have ri data for you gems you'll also need to run:

   gem rdoc --all --overwrite

   If you don't want to rebuild the rdoc for "gem server", add --no-rdoc.

   RubyGems installed the following executables:
   

       C:/Ruby192/bin/gem

   SInce teh problem is most likely with non English code-tables, here is mine for the info:
   C:\Windows\system32>chcp

   Active code page: 852

   C:\Windows\system32>

   Hope it helps,

   Yes, RDoc is the culprit here and upgrading will fix the message.

   Note that when the update process says RubyGems 1.5.0 installed that RubyGems 1.5 is fully functional.
