| http://www.lirmm.fr/~ducour/Doc-objets/ISO+IEC+14882-1998.pdf ( note: 1998 ) page 10, section 2.2 says: |
| |
| 1 The basic source character set consists of 96 characters: the space character, the control characters repre- 15) |
| senting horizontal tab, vertical tab, form feed, and new-line, plus the following 91 graphical characters: |
| a b c d e f g h i j k l m n opqrstuvwxyz |
| A B C D E F G H I J K L M N OPQRSTUVWXYZ |
| 0 12 3 4 5 6 7 8 9 |
| _ { } [ ] # ( ) < > % : ; . ?*+-/^&|~!=,\" |
| 2 The universal-character-name construct provides a way to name other characters. hex-quad: |
| hexadecimal-digit hexadecimal-digit hexadecimal-digit hexadecimal-digit |
| universal-character-name: \u hex-quad |
| \U hex-quad hex-quad |
| The character designated by the universal-character-name \UNNNNNNNN is that character whose character short name in ISO/IEC 10646 is NNNNNNNN; the character designated by the universal-character-name \uNNNN is that character whose character short name in ISO/IEC 10646 is 0000NNNN. If the hexadecimal value for a universal character name is less than 0x20 or in the range 0x7F-0x9F (inclusive), or if the uni- versal character name designates a character in the basic source character set, then the program is ill- formed. |
| |
| |
| So basically: printable ASCII plus 0x00-0x1F, 0x7F-0x9F, was all illegal. |
