character-encodings gem with Ruby 1.9

  1. Hello,

    I tried to install Nikolai Weibull's Ruby Character Encodings Library [1] with Ruby 1.9, but didn't succeed.

    $ sudo gem1.9 install character-encodings
    Building native extensions. This could take a while...
    ERROR: Error installing character-encodings:

    I downloaded the gem, extracted it, added a magic comment at the top of the file and manually called the configure command, that worked.

    What can I do to make it work?

    Do you know that 1.9 has excellent built-in support for character
    encodings?

    Yes, but String#upcase/downcase doesn't work for non-ascii strings.

    Like the OP said, as long as #upcase/#downcase don't work, I'd not call that
    excellent.

    I can certainly understand the constraints of locales/i18n/m17n and the way
    choosen by Matz for Ruby, but I'm getting frustrated by the support (or more
    exactly lack thereof) of Unicode strings.

    I'm looking at friends that have chosen Python and while their way may not be
    the Right One (if there is such a way) but they are enjoying it for common
    usage.

    For a language that toots POLA as a slogan, Unicode support is certainly
    violating every principle there. I'm following 1.9 closely through svn and
    regularely try to use the Unicode support but it is not getting better.

    Sorry if it sounds grumpy but I'm getting frustrated by my favorite language
    and am afraid it shows.
