In order to not accidentally have C strings with \0, an
OFInvalidEncodingException is thrown when trying to get a C string for a

In order to get a C string with \0 anyway, a new method
-[insecureCStringWithEncoding:] is added. file: [027a5197e3] check-in: [6fbc3b18c7] user: js, branch: trunk, size: 20269 [annotate] [blame] [check-ins using] [diff]
