[jboss-jira] [JBoss JIRA] (WFLY-3376) Response encoding UTF-8 returns ISO-8859-1 encoded string

[Stuart Douglas (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-3376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stuart Douglas resolved WFLY-3376.
----------------------------------

    Resolution: Rejected


I find it surprising that this works on other JAX-RS implementations, I would assume that .encoding() sets the content-encoding and not the charset, which is how it seems to be be working at the moment. The spec is kinda vague, but in general when talking about HTTP charset is used to refer to the character encoding, while encoding is used to refer to the content encoding (such as gzip etc).

You should try something like:

type("text/plain; charset=UTF-8")
