§ becomes percent encoded, while it should become a -

[Mikaela]

For example the heading <h2 id="4--toimielimet">4 § Toimielimet</h2> turns into an entry <li><a href="#4-%C2%A7-toimielimet">4 § Toimielimet</a></li> and naturally doesn't work. This can be reproduced at least on:

• https://piraattipuolue.github.io/saannot/

Otherwise I haven't experienced any issues with doctoc, while I love using it with pre-commit, thank you.
