I am unable to find any official documentation on project name restrictions. The only two that can be found are 1. It must be uniqe within the domain and 2. No more than 64 characters.
http://developer.openstack.org/api-ref/identity/v3/?expanded=create-project-detail only states:
"name: The name of the project, which must be unique within the owning domain. A project can have the same name as its domain."
https://github.com/openstack/tempest/blob/master/tempest/api/identity/admin/v3/test_projects_negative.py#L60-L64 shows there is a 64 character limit.
The name must be sent in a valid json which could be any utf-8 character, but does that always work within limits of all backends that use MySQL. MySQL's restrictions state utf-8, but "can contain only characters in the Basic Multilingual Plane (BMP). Supplementary characters are not permitted in identifiers."
https://dev.mysql.com/doc/refman/5.5/en/charset-restrictions.html
Please add documentation for restrictions on project names beyond uniqueness and character count.
