Class Method Details

.decode_utf16le(str) ⇒ Object

Decode a UTF16 string to a ASCII string

Parameters:

  • str (String) —

    The string to convert

# File 'lib/net/ntlm.rb', line 104

def self.decode_utf16le(str)
  Kconv.kconv(swap16(str), Kconv::ASCII, Kconv::UTF16)
end

.encode_utf16le(str) ⇒ Object

Note:

This implementation may seem stupid but the problem is that UTF16-LE and UTF-8 are incompatiable encodings. This library uses string contatination to build the packet bytes. The end result is that you can either marshal the encodings elsewhere of simply know that each time you call encode_utf16le the function will convert the string bytes to UTF-16LE and note the encoding as UTF-8 so that byte concatination works seamlessly.
