-- GNAT was originally developed by the GNAT team at New York University. --
-- Extensive contributions were provided by Ada Core Technologies Inc. --
-- itself, and we want to be able to compile the compiler with old versions
-- of GNAT that did not implement Wide_Wide_Character.
--- This package is not available directly for use in application programs,
--- but it serves as the basis for GNAT.Wide_Case_Utilities and
--- GNAT.Wide_Wide_Case_Utilities, which can be used directly.

- function Is_UTF_32_Digit (U : UTF_32) return Boolean;
- pragma Inline (Is_UTF_32_Digit);
- -- Returns true iff U is a digit that can be used to extend an identifer,

- function Is_UTF_32_Line_Terminator (U : UTF_32) return Boolean;
- pragma Inline (Is_UTF_32_Line_Terminator);
- -- Returns true iff U is an allowed line terminator for source programs,
- -- which means it is in one of the following categories:

-
- function Is_UTF_32_Other (U : UTF_32) return Boolean;
- pragma Inline (Is_UTF_32_Other);
- -- Returns true iff U is an other format character, which means that it
- -- can be used to extend an identifier, but is ignored for the purposes of
- -- matching of identiers. This means that it is in one of the following
- -- categories:
- -- Other, Format (Cf)
-
- function Is_UTF_32_Punctuation (U : UTF_32) return Boolean;
- pragma Inline (Is_UTF_32_Punctuation);

- -- Separator, Space (Zs)
+-- This package is available directly for use in application programs,
