This means that the count that accululates here represents the - -- difference between the length in characters and the length in bytes. - -- This is used for checking the line length in characters. - - function Length_Wide return Nat; - -- Returns the maximum length in characters for the escape sequence that - -- is used to encode wide character literals outside the ASCII range.

A - -- single wide character is scanned. If no error is found, the value - -- stored in C is the code for this wide character, P is updated past - -- the sequence and Err is set to False. If an error is found, then - -- P points to the improper character, C is undefined, and Err is - -- set to True. - - procedure Set_Wide - (C : Char_Code; - S : in out String; - P : in out Natural); - -- The escape sequence (including any leading ESC character) for the - -- given character code is stored starting at S (P + 1), and on return - -- P points to the last stored character (i.e. P is the count of stored - -- characters on entry and exit, and the escape sequence is appended to - -- the end of the stored string).
