<p class="purpose">To compile string constants and comments.</p>
<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. </b>We now take a wide Unicode string and compile a double-quoted I6 string
constant which will print out the same content, or initialise a string array.
</p>
<p class="commentary">A subtly different set of escape characters are used here. It's all trickier
than it might be because of some unfortunate design choices in I6. For
instance, an <span class="extract"><span class="extract-syntax">@</span></span> character can't be escaped as <span class="extract"><span class="extract-syntax">@{40}</span></span> because that
would be expanded too early in the string-reading process, so that it
would still be read as an escape-character <span class="extract"><span class="extract-syntax">@</span></span>, not a literal one.
We therefore have to use <span class="extract"><span class="extract-syntax">@@64</span></span>. This unfortunately goes wrong, however,
when the immediately following character is a decimal digit, because then
we might construct, e.g., <span class="extract"><span class="extract-syntax">@@647</span></span>, and I6 will throw an error: no valid
character has ZSCII code 647. We therefore use the <span class="extract"><span class="extract-syntax">@{...}</span></span> escape to
represent any digit following an <span class="extract"><span class="extract-syntax">@@</span></span> escape. Since no digit is itself
an escape character with side-effects, a vicious circle is avoided.
</p>
<p class="commentary">Initialisation of I6 string arrays has different conventions again: these
behave more like dictionary words and the <span class="extract"><span class="extract-syntax">@@</span></span> escape is not allowed.
