[Ruby] ruby 1.9 utf-8 string support

[godfat (godfat 真常)]

s = '測試'                # => "\346\270\254\350\251\246"
s.encoding                # => <Encoding:ASCII-8BIT>
s.force_encoding 'utf-8'  # => "測試"
s[0]                      # => "測"
s[1]                      # => "試"
s[-1]                     # => "試"
s.size                    # => 2
s.length                  # => 2

('%5s' % s).force_encoding 'utf-8'   # => "   測試"
('%-3s' % s).force_encoding 'utf-8'  # => "測試 "

所以大概是預設 ascii-8bit,
有 utf-8 string 需求才手動強制轉為 utf-8 string 吧，
想必是效能考量...
