It isn't.

The package Ada.Characters.Conversions defines functions To_Character, which
convert a [Wide_]Wide_Character to Character. There are also similar To_String
functions. See ARM A.3.4:

http://www.adaic.org/resources/add_content/standards/12rm/html/RM-A-3-4.html

Anyone using Ada should be familiar with the contents of ARM Annex A, which
defines the standard library.

To convert a single character to an integer value presumes that the character is
a digit. That can be converted more simply with

Character'Pos (Char) - Character'Pos ('0')

Presuming that the digits are contiguous beginning with '0' for Wide_Character,
this would work with Wide_Character'Pos as well.
