UndefinedConversionError when using simple ruby hash

[ksouthworth]

I'm getting the following error when using channel.put and channel.get to pass simple Ruby Hash objects around (1 level of nesting in the hash).

It works for a little while, but as the communication ramps up (4 child processes) I start getting this error consistently.

/.rvm/gems/ruby-2.3.1/gems/cod-0.6.0/lib/cod/iopair.rb:19:in `write': "\xCF" from ASCII-8BIT to UTF-8 (Encoding::UndefinedConversionError)

Do you have sample code that illustrates the problem?
