I met a very strange problem, appear on okhttp version 3.4: under Caused by: Java nio. Charset. IllegalCharsetNameException: %s.I was very confused, why so strange questions.Arguably the server returns the Charset inside is never to appear %s. This is the collapse of the specific log:

I’m pretty sure that the content type is not well-formed, but I have several clients that add the header in this form.

Steps to Reproduce

  1. Start the Hello World Java example
  2. Execute curl http://localhost:8080/hello/test —header ‘Content-Type: text/xml;charset=»utf-8″‘

Expected Behaviour

The response is «Hello test!»
