Hi,

I've been using sphinx v1.7.6 and recently upgraded to v3.0.3

I used conda install to upgrade.

After this when I run 'make html' or 'make latexpdf'  I get follwing mesage 

Running Sphinx v3.0.3

Hi,

Since python3, \u has been considered as unicode-escape sequence. So
you need to escape it like '\\usepackage'.

> 'preamble': '\usepackage{kotex}',

FYI: The raw string also helps you (ex. r'\usepackage{kotex}' ).

Thanks,
Takeshi KOMIYA
