I have a very alpha "UString" class I've got in CVS (in the "shards" project, 
not win32utils) where I've been tinkering with a Windows-only subclass of 
String. It redefines methods like length, size, etc. I've pasted what I've done 
so far below.

Or do you think that's overkill?

# ustring.rb - ALPHA

class UString < String
    include Windows::Unicode
    include Windows::MSVCRT::String

    VERSION = '0.1.0'

    ACP  = CP_ACP
    UTF7 = CP_UTF7
    UTF8 = CP_UTF8

    attr_accessor :encoding

    alias :at :[]

    def initialize(string, encoding = UTF8)
       ustring = multi_to_wide(string, encoding)
       @encoding = encoding
       super(ustring)
    end

    def inspect
       wide_to_multi(self, @encoding)
    end

    def to_s
       wide_to_multi(self, @encoding)
    end

    def to_str
       wide_to_multi(self, @encoding)
    end

    # Length in chars
    def length
       wcslen(self)
    end

    # Size in bytes
    def size
       strlen(wide_to_multi(self, @encoding))
    end

    # Returns the character (not the numeric value)
    def [](n)
       wide_to_multi(self, @encoding).at(n, 1)
    end
end
