Most of them are +commands for positioning and text writing. These commands are tolerant +of whitespace. Optionally, syntactical space can be inserted before, +after, and between the command letter and its arguments. All of these +commands are stackable; i.e., they can be preceded by other simple +commands or followed by arbitrary other commands on the same line. A +separating syntactical space is necessary only when two integer +arguments would clash or if the preceding argument ends with a string +argument. +</p> +<dl class="table"> +<dt><code class="code">C <var class="var">id</var>‹<span class="r">whitespace</span>›</code></dt> +<dd><p>Typeset the glyph of the special character <var class="var">id</var>.
