In the "custom ad text" for the ad to Bookapy at the end of a story on SOL, some characters disappear.
Both the ( and ) disappear. The [ displays, but the ] disappears. And both the { and } disappear.
I was trying to put something in parentheses, but they didn't show up. Then I tried the others mentioned above as a substitute. I ended up using em-dashes, but they're a force-fit.
Are those characters not allowed or is there a bug?
