→Interaction between TeX and lua: 'expand' tex macros
</texcode>
This can be avoided by using a TeX comment instead of a lua comment. However, working under normal TeX catcodes poses a bigger problem: special TeX characters like \letterampersand&, \letterhash#, \letterdollar$, \{, \}, etc., need to be escaped. For example, \letterhash\ # has to be escaped with <code>\string</code> to be used in <code>\ctxlua</code>.
<texcode>
\ctxlua
