Does the KOReader support the vertical read for Chinese word?

Hi designer,

Does KOReader support the vertical read for Chinese word?
Usually we will add the setting in the CSS file in the EPUB:
writing-mode: vertical-rl;
-epub-writing-mode: vertical-rl;
-webkit-writing-mode: vertical-rl;
But I seems like KOReader doesn't support such setting? Can it be added?

Thanks.

@TnS-hun Would you happen to know if MuPDF does this? Long-term I'd like to look into engine selection (see #3345) but if there's a concrete advantage like this there'd be an extra incentive. ;-)

I don't think MuPDF supports that. Those string can't be found in the latest version (except for some svg generation dev. feature).

And here is a comment from a related bug:

We are not likely to ever support vertical writing in the EPUB viewer.

Sort of similar for crengine I'd say, unfortunately for the OP.

Upstream "iisue", nothing we can do :).
