Substitution issue

[NoralK]

I have the following markup:

.. only:: not latex

    .. |mychar| unicode:: U+ABCD

.. only:: latex

    .. |mychar| raw:: latex

        {\Symbola\char"ABCD}

I am getting the following error when I compile make html or make latex:

mychar.txt:7: ERROR: Duplicate substitution definition name: "mychar".

I would expect when I make latex then the html section would not be generated and when I make html the latex section would not be generated.

Any thoughts how to fix this? BTW - I am using xelatex to generate the PDF.

it's a current behavior of only directive (see also #1488).

only is a 'rendering control marker' at 'writing stage' instead of 'reading stage'.
Because of that, all definitions under only directive will be parsed at 'reading stage'.

So, to avoid this error, you can use custom sty file for latex to define unicode symbols (Although I'm not familiar to latex, it will work).
