ZENMAP FAILED TO OPEN DEVICE CODE
If pcap_init() is not called, strings are treated as being in the local ANSI code page on Windows, pcap_lookupdev() will succeed if there is a device on which to capture, and pcap_create() makes an attempt to check whether the string passed as an argument is a UTF-16LE string - note that this attempt is unsafe, as it may run past the end of the string - to handle pcap_lookupdev() returning a UTF-16LE string. If pcap_init() is called, the deprecated pcap_lookupdev() routine always fails, so it should not be used, and, on Windows, pcap_create() does not attempt to handle UTF-16LE strings. On Windows, the local character encoding is the local ANSI code page.

On UNIX-like systems, the local character encoding is assumed to be UTF-8, so no character encoding transformations are done. PCAP_CHAR_ENC_UTF_8 Treat all strings supplied as arguments, and return all strings to the caller, as being in UTF-8. PCAP_CHAR_ENC_LOCAL Treat all strings supplied as arguments, and return all strings to the caller, as being in the local character encoding. It takes an argument giving options currently, the options are: It also supports saving captured packets to a ``savefile'', and reading packets from a ``savefile''. All packets on the network, even those destined for other hosts, are accessible through this mechanism. The Packet Capture library provides a high level interface to packet capture systems.
