Output Module and Render Settings template names do not currently support Unicode characters.
Unicode support is being added to After Effects progressively, over several versions, as each text field in the application has to be updated separately. There are over 130 different text fields in After Effects, and about 4/5 of them have been converted. The release notes for each version have generally not called out these changes because they tend to be minor, but a major step was completed in After Effects CC (12.0) of supporting Unicode in file names and paths (see the "Unicode conversion for robust support for characters" paragraph).
You're welcome to submit a feature request for any particular field to be updated: http://adobe.ly/feature_request
