It returns "" in such a case in Emacs 24. Emacs 23 returned
nil but that behavior was fixed because Unicode Standard
Annex #44 (Unicode Character Database) says as below:
4.2.8 Default Values
[...]
* For miscellaneous properties which take strings as
values, such as the Unicode Name property, the default
value is a null string.
