I see how to get a close curly single quote with long press, but how do you get an open curly single quote? The long press for the double quote key gives both open and close as options but for the single quote key only gives the close option.
Use the backslash (\) key.
For the ’ key, Bloom is giving you U+02BC (Modifier letter apostrophe).
For the \ key, Bloom is giving you U+2018 (Left single quotation mark) and U+2019 (Right single quotation mark).
Thanks. Never knew that!
