nsIIDNService interface.

 IDN (Internationalized Domain Name) support. Provides facilities
 for manipulating IDN hostnames according to the specification set
 forth by the IETF.

Methods

 This is the ToUnicode operation as specified in the IDNA proposal,
 with an additional step to encode the result in UTF-8.
 It takes an ACE-encoded hostname and performs ToUnicode to it, then
 encodes the resulting string into UTF8.
AUTF8String convertACEtoUTF8(in ACString input) 
 Normalizes and converts a host to UTF-8 if the host is in the IDN
 whitelist, otherwise converts it to ACE. This is useful for display
 purposes and to ensure an encoding consistent with nsIURI::GetHost().
 If the result is ASCII or ACE encoded, |isASCII| will be true.
AUTF8String convertToDisplayIDN(in AUTF8String input, out boolean isASCII) 
 Prepares the input hostname according to IDNA ToASCII operation,
 the input hostname is assumed to be UTF8-encoded.
ACString convertUTF8toACE(in AUTF8String input) 
 Checks if the input string is ACE encoded or not.
boolean isACE(in ACString input) 
 Performs the unicode normalization needed for hostnames in IDN,
 for callers that want early normalization.
AUTF8String normalize(in AUTF8String input)
