I seem to be unable to send JSON data for a text field containing an apostrophe. It works fine with no apostrophe but I see the server response says “internal error” when I send it with the apostrophe or with a slash and the apostrophe which I thought was correct for JSON data to come through correctly. See images and notice FRASER’S GROVE, FRASER' GROVE, FRASERS GROVE at top right in first visible line and server response lower in image.
Looks like there is a bug. You can work around this for the time being using an HTML entity like this:
FRASER'S GROVE - i.e. swap the ’ for
Hope this helps til we can fix the underlying issue.
