+
+Note that brackets encoding only applies to program text. Within comments,
+brackets are considered to be normal graphic characters, and bracket sequences
+are never recognized as wide characters.
If no @option{-gnatW?} parameter is present, then the default
representation is normally Brackets encoding only. However, if the
parameter.
@end table
+
+When no @option{-gnatW?} is specified, then characters (other than wide
+characters represented using brackets notation) are treated as 8-bit
+Latin-1 codes. The codes recognized are the Latin-1 graphic characters,
+and ASCII format effectors (CR, LF, HT, VT). Other lower half control
+characters in the range 16#00#..16#1F# are not accepted in program text
+or in comments. Upper half control characters (16#80#..16#9F#) are rejected
+in program text, but allowed and ignored in comments. Note in particular
+that the Next Line (NEL) character whose encoding is 16#85# is not recognized
+as an end of line in this default mode. If your source program contains
+instances of the NEL character used as a line terminator,
+you must use UTF-8 encoding for the whole
+source program. In default mode, all lines must be ended by a standard
+end of line sequence (CR, CR/LF, or LF).
+
+Note that the convention of simply accepting all upper half characters in
+comments means that programs that use standard ASCII for program text, but
+UTF-8 encoding for comments are accepted in default mode, providing that the
+comments are ended by an appropriate (CR, or CR/LF, or LF) line terminator.
