Note: The following information only applies to Helix ALM 2017.1.0 and TestTrack 2016.1 and earlier.


One of the following errors is returned when validating the Helix Versioning Engine/Perforce source control integration connection in Helix ALM or TestTrack:

'Unicode server permits only Unicode enabled clients'

'Unicode clients require a Unicode enabled server'

All actions may also be disabled on the Helix ALM item Source Files tab if attached changelists have Unicode characters in the description. 


The P4CHARSET registry key (Windows) or environment variable (Unix) value on the computer running the Helix ALM/TestTrack Client does not match the Unicode mode setting for the Helix Versioning Engine/Perforce server.


Run p4 commands to update the P4CHARSET value.


Note: Only users familiar with Windows administration should make changes to the registry.

Enter one of the following P4 commands to update the Software\Perforce\Environment\P4CHARSET key.

Unicode server permits Current user only p4 set P4CHARSET=auto
All users p4 set –s P4CHARSET=auto
