Safari switching slides broken if id of a slide contains cyrillic

[certainlyakey]

In Safari, both mobile and desktop, if you have some cyrillic symbols inside a slide's id, strange characters appear in address bar instead of proper id value and it's possible to switch only a few slides - after that the slideshow jumps to the last slide.

I noticed that because I use Pandoc to create presentations and it automatically places whatever is the heading of the slide into the id attribute of a slide section tag.

Here's a test presentation.

As a workaround, it would be great to have an option to turn off the section ids as hashes and leave only slides' numbers.

I recommend setting the history config value to false in your case.

This did bring up an interesting issue though and I've made a few changes to restrict which characters reveal.js picks up for named links (a-z, 0-9 and basic punctuation). I've also patched an issue where a malformed hash in the URL would cause reveal.js to thrown syntax errors.

OK, thank you! Turning history off solves the issue.
