# Name

Within a project, each object has a name, which is a UTF-8 string which must not match the regular expression `[\x00-\x1F]`. This means non-printable characters like whitespace tabs and newlines are not allowed. Object names need not be unique within the same project.

The name of an object is returned by the "describe" method, and modified by the "rename" method.
