DocsIn C0, only the following values will be used:
| 00/09 | HT | HORIZONTAL TABULATION |
| 00/10 | NL | NEW LINE |
| 01/11 | ESC | (ESCAPE) |
In C1, only the following value will be used:
| 09/11 | CSI | CONTROL SEQUENCE INTRODUCER |
[The alternate 7-bit CSI encoding 01/11 05/11 is not used in Compound Text.]
No control sequences are defined in Compound Text for changing the C0 and C1 sets.
A horizontal tab can be represented with the octet 00/09. Specification of tabulation width settings is not part of Compound Text and must be obtained from context (in an unspecified manner).
[Inclusion of horizontal tab is for consistency with the STRING type currently defined in the ICCCM.]
A newline (line separator/terminator) can be represented with the octet 00/10.
[Note that 00/10 is normally LINEFEED, but is being interpreted as NEWLINE. This can be thought of as using the (deprecated) NEW LINE mode, E.1.3, in ISO 6429. Use of this value instead of 08/05 (NEL, NEXT LINE) is for consistency with the STRING type currently defined in the ICCCM.]
The remaining C0 and C1 values (01/11 and 09/11) are only used in the control sequences defined below.
