Either way is fine by me (all those "" are > really one and the same string, so they don't waste memory). 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. ^^^^^^^^^^^^^ --- Kenichi Handa handa@m17n.org
