more unicode pathways

I forgot a couple of unicode pathways to check:

• sending data in a GET request from chrome — check
• sending data in a POST request from chrome — check
• sending data in a GET request from node.js — check
• sending data in a POST request from node.js — failed

..the failure there is not node, but me. I was not sending the proper header information in my _.wget utility. Fixed. I should probably put nodeutil.js in the myutil github repo..
