Hylian or Borginian in the UCSUR.

I am not sure if those are within scope of the UCSUR. Hylian is a conscript used in The Legend of Zelda... actually multiple conscripts as you can see here. Similar to the Standard Galactic Alphabet from Commander Keen and Minecraft. Though this opens the door for the mess that's Inkling script

Borginian is a conscript from the Ace Attorney series from the fictional country of Borginia from Dino Crisis. As far as anyone knows it's has no phonetic meaning and is internally mapped to Cyrillic codepoints. There are only 17 letters in the script so it can't be based on Latin, Cyrillic or Kana. Here's the font I grabbed from one of the game's files.

I think the question mark looking letter is supposed to be a question mark
