Alternative Character Set

Draft incorporates an alternative character set that provides useful symbols. An ‘alternative’ character is specified by preceding one of a set of normal alphanumeric characters by the tilde (~) sign. For example, the steelwork I-beam symbol could be defined as a TEXP by setting the BTEX attribute as:

BTEX ’~I’

The tilde may be input as normal text by doubling it (that means, ’~~’ produces a single tilde). Normal text, intelligent text and ‘alternative’ characters may be input in any combination.

See Figure 15:1 below for the full list of available symbols.
