 \item Support for internationalized domain names (RFCs 3454, 3490,
 3491, and 3492) has been added. The ``idna'' encoding can be used

-In addition, the \module{socket} has been extended to transparently
-convert Unicode hostnames to the ACE before passing them to the C
-library. In turn, modules that pass hostnames ``through'' (such as
-\module{httplib}, \module{ftplib}) also support Unicode host names
-(httplib also sends ACE Host: headers). \module{urllib} supports
-Unicode URLs with non-ASCII host names as long as the \code{path} part
