+-- This is an Ada 2012 package defined in AI05-0137-1. It is used for encoding
+-- and decoding String values using UTF encodings. Note: this package is
+-- consistent with Ada 95, and may be included in Ada 95 implementations.
+
+package Ada.Strings.UTF_Encoding.Strings is
+ pragma Pure (Strings);
+
+ -- The encoding routines take a String as input and encode the result
+ -- using the specified UTF encoding method. The result includes a BOM if
+ -- the Output_BOM argument is set to True. All 256 values of type Character
+ -- are valid, so Encoding_Error cannot be raised for string input data.
+
+ function Encode

+ Output_Scheme : Encoding_Scheme;
+ Output_BOM : Boolean := False) return UTF_String;

+ -- the Output_Scheme parameter.
+
+ function Encode

+
+ function Encode
+ (Item : String;
+ Output_BOM : Boolean := False) return UTF_16_Wide_String;
+ -- Encode String using UTF_16 encoding
+
+ -- The decoding routines take a UTF String as input, and return a decoded
+ -- Wide_String. If the UTF String starts with a BOM that matches the
+ -- encoding method, it is ignored. An incorrect BOM raises Encoding_Error,
+ -- as does a code out of range of type Character.
+
+ function Decode
+ (Item : UTF_String;
+ Input_Scheme : Encoding_Scheme) return String;
+ -- The input is encoded in UTF_8, UTF_16LE or UTF_16BE as specified by the
+ -- Input_Scheme parameter. It is decoded and returned as a String value.
+ -- Note: a convenient form for scheme may be Encoding (UTF_String).
