--  Helper functions to deal with unicode strings


package Adagio.Unicode is

   Invalid_encoding : exception;
   
   -- Returns a Latin1 string from a G2 encoded string

   -- It can be a UTF8 encoded string or a

   -- 16 bit (endianness applies then) raw unicode character string.

   -- The 16#ff# selector must be the first character in that case.

   -- May raise exception if Latin1 can't hold the resulting string.

      return String;

   -- Returns a Utf8 encoded string from Latin1 (Ada default)
