[Ironruby-core] Encoding problem

Hi,

I don't really know the solution to your question, but this might help:

ë is Unicode U+00EB, which is 0xC3AB in UTF-8 (so we are dealing with
unicode rather than utf-8, which I assume is because IronRuby uses the
immutable .NET strings internally with Unicode encoding).

The errors are expected if your default encoding is US-ASCII because it does
not contain ë (and uses single bytes, so the 0x00EB would be broken into two
bytes and your script would choke on the second 0xEB) : you will need to set
your encoding to something compatible, like utf-8.

I don't quite know how to do that properly in IronRuby, but in CRuby 1.9 you
could use "magic comments" in your ruby file and in 1.8 something like
$KCODE='u' could work. You might also be able to drop back into .NET and set
the encoding there, but I'm not sure how that affects IronRuby assemblies.

I would start with $KCODE = 'u' Let me know how that works for you.
