Summary

Symptoms

The following appears in the atlassian-confluence.log:

1 fileSystemEncoding = ANSI_X3.4-1968

Another symptom:

  • Workbox Notification shows ERR_CONTENT_DECODING_FAILED

  • When exporting to PDF, texts that include special characters such as accents do not get printed. For example, instead of printing é and ü, the PDF export will display e and u.

Diagnosis

Run the command su -l -c locale confluence to find the following result:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 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=

Cause

The filesystem encoding in Confluence has been set to ANSI_X3.4-1968. This encoding can cause issues in Confluence as the encoding supported in Confluence is only UTF-8

Solution

Resolution

  1. In setenv.sh, add the following JVM parameter by editing the line below before the export CATALINA_OPTS parameter:

    1 2 3 4 CATALINA_OPTS="-Dfile.encoding=UTF-8 -Djavax.servlet.request.encoding=UTF8 ${CATALINA_OPTS}" export LC_ALL=en_US.UTF-8 export LANG=en_US.UTF-8 export LANGUAGE=en_US.UTF-8

    (If you are running an old Confluence's version, you might need to use the parameter below instead of the CATALINA_OPTS variable:)

    1 JVM_SUPPORT_RECOMMENDED_ARGS="-Dfile.encoding=utf-8
  2. Take the following additional steps if you use Redhat or Ubuntu:

    • In Redhat 6.x (RPM-Based distributions), set the LANG and LC_ALL values in /etc/sysconfig/i18n as follows:

      1 2 LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8"
    • In Redhat 7.x (RPM-Based distributions), run the following command:

      1 sudo localectl set-locale LANG="en_US.UTF-8"
    • In Ubuntu (Debian and Debian-based distributions), set the LANG and LC_ALL values in /etc/default/locale as follows:

      1 2 LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8"

You must use the default locale entry that is common to your language for the UTF-8 character set, the choice en_US.UTF-8 is the correct choice for US English language, while your language may vary
