<p>Right now, I cannot write a Lua function <code>quote_array</code> that converts an array of strings to a string that (when used as the argument to a macro) will be interpreted as the initial array.  This is because \x1a (ASCII unit separator) cannot be escaped.</p>
<p>One solution would be to allow \x1a to be escaped by doubling it, and have <code>%{quote:…}</code> do this automatically.</p>
