Terminal symbols of the lexical, RegExp, and numeric string grammars 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.
