[Tex/LaTex] How to modify the default LaTeX package parameters of Sphinx

Question

I want to generate pdf by using Sphinx. Sphinx generates pdf through LaTeX. But I have to add unicode=true to package hyperref of LaTeX:

\usepackage[unicode=true]{hyperref}

But Sphinx has generated a default sphinx.sty file that containing configuration of package hyperref when I ran make latex. I have to add unicode=true to this file every time after running make latex with Sphinx, then make all-pdf with latex to generate the pdf.

Is there any method to modify this parameter of package hyperref in the Sphinx's configure file, so that I can run make latexpdf with Sphinx to finish the two steps once?

Answer 1

just add \hypersetup{unicode=true} to conf.py:

latex_elements = {
    'preamble': '''
        \\hypersetup{unicode=true}
     '''
}
