Our Japanese customer needs to change the group name in the OPC server to Chinese characters.
The OPC server connected to this project is Yokogawa.ExaopcAESTARDOMFCX.
The name of the group has been changed to the format of letters plus Chinese characters. It's like "RST life".
So I would like to ask, does the Chinese characterization of group names affect the long-term OPC communication?
※: We have no problem with the test communication. But just worry about whether it will affect the long-term operation of the site. Because this is our first attempt to change the name of the group from full letters to letters plus Chinese characters.

Hi,
Hard to give you a yes/no anwser.
We always did our best to accommodate non-latin characters in the configuration, fine in descriptions and labels, not always possible in configuration item names.
In the particular case of the OPC client, there is also the constraints from the OPC specification itself. In the past, we faced OPC servers with hardcoded group names not complying with our object names' syntax constraints or OPC spec's constraints.
At the time we have added a property 'Group name imposed by the server' - in the advanced tab of an OPC group configuration in the Application Explorer. This property allow you to define a group name that will be used at runtime instead of the name of the group configuration item.
From the help:
Group name imposed by the server - Use this property to designate the corresponding OPC group if the OPC server imposes a non-compliant group name (imposed name too long or comprising characters that are not allowed).
If the OPC server supports non-latin characters in group names, this property may be the solution on the PcVue side.
