Here's the code. Thanks to Mark Hubbart for getting me started.  
(Note: I don't include OSX because I haven't explained that yet to  
the audience for this code.)

require 'osx/cocoa'
require 'test-strings/copy-util'

MAC_OS_ROMAN_ENCODING=30
UTF8_ENCODING=4

def copy(string)
   copy_with_encoding(string, MAC_OS_ROMAN_ENCODING)
   true
end

#Example: unicopy %w{ 03b4 03d4 03a6 }
def unicopy(hex_string_array)
   assert_names_of_acceptable_length(hex_string_array)
   copy_with_encoding(utf8(hex_string_array), UTF8_ENCODING)
   true
end

# Utilities

def utf8(hex_string_array)
   number_array = hex_string_array.collect do | hex_name |
     hex_name.to_i(16)
   end
   number_array.pack("U*")
end

def copy_with_encoding(string, encoding)
   data = OSX::NSData.dataWithRubyString(string)
   ns_string = OSX::NSString.alloc.initWithData(data, :encoding,  
encoding)
   pb = OSX::NSPasteboard.generalPasteboard
   pb.declareTypes(["NSStringPboardType"], :owner, nil)
   pb.setString(ns_string, :forType, "NSStringPboardType")
end
