When I'm in Card Database and I click on "Acid Hands" McGillicutty (for example) the link seems broken and it opens Deckbox's main page (with error "The page you are looking for does not exist") instead of a page with that card. It's because the link looks like that:

https://deckbox.org/wow/"Acid%20Hands"%20McGillicutty

To fix that the " should be replaced with browsers friendly percent-encoding %22, see below:

https://deckbox.org/wow/%22Acid%20Hands%22%20McGillicutty

Same thing with cards with apostrophe in their names (fix: changing ' to %27).

A'dal, just for example:
https://deckbox.org/wow/A'dal
https://deckbox.org/wow/A%27dal

But something is bad here - the tooltip with card info is showing only on that "broken" link. So either it opens a proper page, or either it correctly shows a tooltip on hover :/

PS: I use Firefox and Xubuntu 16.10

EDIT: Or just ignore percent-encoding and just change " to " and ' to '
I think that works in WHI Database (both, links and tooltips are OK there).
