Nope - must be a bug in IronRuby:
*MRI v1.9.2:*
*
irb(main):001:0> str = "%s" % "\u00c2"
=> "\u00C2"
irb(main):002:0> str.encoding
=> #<Encoding:UTF-8>
irb(main):003:0> puts str
Â
*
*IronRuby v1.1.3:*
*
irb(main):001:0> str = "%s" % "\u00c2"
=> "\xC2"
irb(main):002:0> str.encoding
=> #<Encoding:IBM437>
irb(main):003:0> puts str
Encoding::InvalidByteSequenceError: character U+00C2 can't be encoded in
IBM437
from (irb):3:in `puts'
from (irb):3
from C:/IronRuby/bin/irb:13
*
*String#%* seems to handle encoding differently between the two Rubies. If
I can figure it out, I'll send a pull request.
