Full JSON export contains Unicode unsupported by Godot4 JSON parser

[Dave]

First, Thank you for this great tool, I'm having a lot of fun with it!

Description

When importing a fully exported JSON into something like Godot 4 I receive an error:

"Parse JSON failed. Error at line 0: Invalid UTF-16 sequence in string, unpaired trail surrogate"

I tracked it down to this following line:

{"id":"marker25","name":"Goldemeagon Idol","legend":"An ancient idol. It has an inscription, but no one can translate it:\n <div style="font-size: 1.8em; line-break: anywhere;">\udc1b\ud802𐠃\ud802\ud802\ud802\ud802\ud802\ud802𐠵\udc26𐠿𐠙\udc18𐠎\udc01\udc13\udc16\udc1d\udc21\udc26\udc11𐠑\udc38\udc17\udc2c\ud802\ud802\ud802𐠫\ud802\ud802𐠷𐠬\udc17𐠮𐠎 𐠦𐠱\ud802𐠘\ud802\ud802𐠂\udc0e\udc0c𐠊\udc19"}

I'm guessing the 'Goldemeagon' is random as well as the marker but the main issue is the '\ud802' could it be replaced with something else?

Steps to reproduce

1. Create a map
2. Export full JSON
3. Open this page: http://jsonviewer.stack.hu/
4. Copy the json data into the 'text' tab and search for 'ud802'

Expected behaviour

A happy JSON parser, specifically one that does this: (<UTF-16 Value> & 0xfffffc00) != 0xd800

Actual behaviour

JSON parser doesn't like the unicode character
This is what actually causes an error in the JSON parser: (<UTF-16 Value> & 0xfffffc00) == 0xd800

Attached JSON file

test.json.zip

Generator version

1.89.11

Browser version

Chrome Version 109.0.5414.119 (Official Build) (64-bit)

Thanks for any help!

Hello. This marker has a bunch of random rare Unicode chars, that's expected. I see that this particular char is Invalid Character. So I believe the issue is that system doesn't know this character, probably it doesn't support the latest Unicode. In any case this is a valid Unicode char, I am not quite sure why JSON parser doesn't like it. Do you have any suggestions?

Thanks for getting back to me so quickly!

If it's a valid Unicode then you should not change anything. I have a workaround for this temporarily and I can look into this on the Godot side for a more permanent solution.

Thanks again,

Dave
