Special characters in html style json

Im using a Norwegian keyboard with some letters like å æ ø that is not in the English keyboard. Is there a command I can run to make the Learning App display these special characters from the data.json file and the data2.json from GitHub file?

I know that in my case (QWERY keyboard) if you press and hold the character on the keyboard you get a pop-up option to select the character that you want.

For example, if I press and hold down the letter a on my keyboard I get these options:
à, á, â, ä, æ, ã, å and ā

I can get them to show up in a json file too.

Hello,
A HTML browser would render Å as Å .
Class JSONEncoder, and JSONDecoder would handle \u{C5} as Å , where C5 is a UTF-8 value in hexadecimal. See: JSONEncoder and JSONDecoder at developer.apple.com
Hope this helps. I did not check out the Learning App.
