Websphere 8.5.5 UTF-8 encoding issue

问题

I have a problem with my application on Websphere 8.5.5. It's a spring rest application that is used to send email. In my service I receive the mail details and I use spring to forward it to the receivers. It works fine but when I try to send messages with non ascii character the message arrives with the special characters replaced by a question mark. The UTF-8 encoding doesn't work. In my pc the application runs on Liberty Profile server and initially it doesn't work either. I googled the problem and found that spring needs a filter to interpret the special characters, so I added this lines to my web.xml

<filter>
      <filter-name>CharacterEncodingFilter</filter-name>
      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
      <init-param>
          <param-name>encoding</param-name>
          <param-value>UTF-8</param-value>
      </init-param>
  </filter>
  <filter-mapping>
       <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/</url-pattern>
  </filter-mapping>

On Liberty works fine but when I deploy the app on Websphere it doesn't.

I tried to directly translate the message in utf-8 with the String constructor:

new String(byteArray, "UTF-8")

and the same thing happens. It works on liberty but it doesn't on Websphere. Then I found that you can force WebSphere to use UTF-8 by adding these JVM Arguments:

-Dclient.encoding.override=UTF-8
-Dfile.encoding=UTF-8

like explained in this answer: Character encoding issues on websphere

I set the parameters on my server and restart like explained in many guides I found on the internet, but obviously it didn't work.

This is the output of locale command in linux machine where WAS run:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I'am stuck and do not know what else to try.

Any help would be appreciated.

The encoding.properties file located at <PROFILE_ROOT>/properties is one more location that contains encoding settings. The default value (for English) is en=ISO-8859-1. Update this to en=UTF-8 and restart the server.
