Unicode Client Error Occurs When Configuring the TestTrack Integration with Perforce

Article ID: 544  |  Last updated: 29 Dec, 2014


The following error is returned when configuring the TestTrack integration with Perforce:

'Unicode clients require a Unicode enabled server.'

The error is returned when you click Validate Connection in the User Options category or select the Project Paths category in the Configure SCC Integration dialog box.


The Perforce server is not running in Unicode mode but the P4CHARSET registry key (Windows) or environment variable (Unix) is set to a Unicode value.


Clear the value set in P4CHARSET.


Note: Incorrectly editing the registry may severely damage your system. We strongly recommend that only experienced Windows administrators make changes to the registry.

Execute the following p4 commands.

  • To clear the HKEY_CURRENT_USERSoftwareperforceenvironmentP4CHARSET key, enter:
    P4 set -s P4CHARSET=none
  • To clear the HKEY_LOCAL_MACHINESoftwareperforceenvironmentP4CHARSET key, enter:
    P4 set P4CHARSET=none


Execute the following p4 command:
export P4CHARSET=none
