7.3.3.1 Special characters

‘$’ is ignored in PreTeX for compatibility with LaTeX, and ‘%’ introduces a comment. Hence they are the only symbols which have to be quoted by a ‘\’. The following characters should also be quoted to produce good LaTeX files, but are accepted by PreScript: ‘_’, ‘&’, ‘#’.

Note that inside a command, like \textbf, the quotation mechanism does not work in PreScript (\textrm{#$%} writes ‘#$%’) though LaTeX still requires quotation. Hence whenever special characters or symbols are introduced, they should be at the outer most level.
