The repos_copy utility reads metadata from the repository and writes the data out to files in Unicode (UTF-8 format). It also reads such files and loads them into the repository in Unicode (UTF-8 or UCS-2, as the underlying repository database dictates).
Repos_copy files created with InterChange Server Express version levels earlier than 4.1.1 can be loaded into the repository correctly only if the dates and times for the component schedules are in full US format. (This is usually not a problem. Repos_copy saves all schedule dates in full US format only. The incompatibility may arise if the repos_copy files have been manually edited.)
In addition, when deploying 4.1.1 repositories, be sure to specify the character encoding with the '-nc' option.
