I’m trying to use the waz-storage gem for talking to Windows Azure  
storage  
services, but it uses kconv and there’s a problem with the toutf8 mix-in  
method, which is trying to call NKF.nkf, which is not defined.

Repro:

irb(main):001:0\> require ‘kconv’  
=\> true  
irb(main):002:0\> “foo”.toutf8  
NoMethodError: undefined method `nkf' for NKF:Module from C:/ironruby/lib/ruby/1.8/kconv.rb:187:in`toutf8’  
from C:/ironruby/lib/ruby/1.8/kconv.rb:327:in `toutf8' from (irb):2 from C:/ironruby/lib/ruby/1.8/irb.rb:150:in`eval\_input’

from C:/ironruby/bin/iirb:13

Is there another way of converting to UTF-8 which is support in  
IronRuby?

Cheers,  
Mark

Maybe the .NET’s System.Text.Encoding class:

> > > bytes = Encoding.convert(Encoding.ASCII, Encoding.UTF8,  
> > > Encoding.ASCII.get\_bytes(“Hello”.to\_clr\_string))  
> > > =\> [72 (Byte), 101 (Byte), 108 (Byte), 108 (Byte), 111 (Byte)]  
> > > Encoding.UTF8.get\_string(bytes)  
> > > =\> ‘Hello’

I’ll give that a try, thanks.
