This PR adds a long description up to 40,000 maxLength and 4,000 graphemes, while retaining the existing short description field as-is for highest backward compatibility.
Apple and Google both have 4,000 character limits on their descriptions.
For the ATStore listing lexicon it’s much larger, but every single one would fit into a 4,000 cap. Right now, there are 77/178 (43%) claimed listings that have descriptions >300 characters and 131/315 (42%) unclaimed listings over the 300 character limit.
