I just re-found this in ECMA-48 and I'm trying to work out if they're
relevent to double width as well as double spacing... not that I'm that
keen on them :-(
8.3.112 SCS - SET CHARACTER SPACING
Notation: (Pn)
Representation: CSI Pn 02/00 06/07
No parameter default value.
SCS is used to establish the character spacing for subsequent text.
The established spacing remains in effect until the next occurrence
of SCS, or of SELECT CHARACTER SPACING (SHS) or of SPACING INCREMENT
(SPI) in the data stream, see annex C.
Pn specifies the character spacing.
The unit in which the parameter value is expressed is that established
by the parameter value of SELECT SIZE UNIT (SSU).
8.3.139 SSU - SELECT SIZE UNIT
Notation: (Ps)
Representation: CSI Ps 02/00 04/09
Parameter default value: Ps = 0
SSU is used to establish the unit in which the numeric parameters of
certain control functions are expressed. The established unit remains
in effect until the next occurrence of SSU in the data stream.
The parameter values are
0 CHARACTER - The dimensions of this unit are device-dependent
1 MILLIMETRE
2 COMPUTER DECIPOINT - 0,035 28 mm (1/720 of 25,4 mm)
3 DECIDIDOT - 0,037 59 mm (10/266 mm)
4 MIL - 0,025 4 mm (1/1 000 of 25,4 mm)
5 BASIC MEASURING UNIT (BMU) - 0,021 17 mm (1/1 200 of 25,4 mm)
6 MICROMETRE - 0,001 mm
7 PIXEL - The smallest increment that can be specified in a device
8 DECIPOINT - 0,035 14 mm (35/996 mm)
