5.1.5 Grammar Notation
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.
