Fieldtype display_field() function converting to htmlentities()?

Question

I'm having some trouble where my display_fields() function is converting my json encoded data from $data into htmlentities().

Here's my function:

function display_field($data)
{
    error_log($data);
}

Return:

[{"approved":true}]

Stored in database as:

[{"approved":true}]

The comments on the official documentation page note the following:

Just a note that on display_field the data has htmlspeciachars on it if you’re trying to deserialize or decode_json so make sure you do this:

htmlspecialchars_decode($data)

Before you try and decode it.

So to apply that same thing in your case, you'd need:

function display_field($data) { error_log( htmlspecialchars_decode($data) ); }
