I did find this workaround (which works for me):

if RUBY_VERSION =~ /1.9/
  Encoding.default_external = Encoding::UTF_8
  Encoding.default_internal = Encoding::UTF_8
end

But I think that later it causes a different error so I'd rather not use it and just try to understand what's really wrong here. I know for sure this same code works on a different system...

As a workaround you can set utf8 locale in your system:

export LANG="C.UTF-8"
export LC_ALL="C.UTF-8"

More info about this is here

That's the thing - I don't want a workaround, I want to understand the reason for the problem and solve it.

Without viewing the exact file (well, gemspec in this case) I cannot say for sure but the most likely cause of this is that the file is encoded using utf8 but Ruby is trying to read the file and assuming it is encoded using ASCII. You cannot solve this problem as such and the best method to deal with it is to use the workaround which tells ruby to assume the default is utf8.
