we will try to add the support for Korean, Japanese And Chinese soon and you will be provided with the assembly (dll file) that you will include in your project. In the meanwhile you can do the following as a workaround:
If we are talking about the Group category management in the MonoX administration find the following file /MonoX/Admin/GroupCategoryManager.aspx
and remove the line below:
ErrorMessage='<%$ Code: AdminResources.GroupCategoryManager_validateName %>'></
I hope this will allow you to get by the issue, if not let us know. Stay tuned for the patch assembly.
