Terminal symbols are shown in fixed width
font, both in the productions of the grammars and throughout this specification whenever the
text directly refers to such a terminal symbol. These are to appear in a script exactly as
written. All terminal symbol code points specified in this way are to be understood as the
appropriate Unicode code points from the Basic Latin range, as opposed to any similar-looking
code points from other Unicode ranges.
