Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty profile                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Certain characters are displayed        *
  *                      incorrectly depending upon the          *
  *                      inbound URI and the request encoding    *
  *                      set.                                    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the inbound request URI is not UTF-8 encoded (for example,
  if requested via Microsoft Internet Explorer) but the request
  encoding is set to UTF-8 then characters whose encoded values
  are different in ISO-8859 vs UTF-8 will be displayed
  incorrectly in the response (for example: n-tilde characters).
  

Problem conclusion

• The WebContainer code has been updated and the characters are
  encoded and decoded correctly based on the request encoding
  set. To get this new behavior the following new WebContainer
  custom property needs to be set in server.xml.
  
  <webContainer decodeParamViaReqEncoding="true"/>
    (default =false)
  
  The instructions to set the new property are here,

  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.5.5.1.  Please refer to the Recommended Updates
