This is the characters wildcard that I currently use in about 90% of my gens, slightly modified to remove things that only work on my machine (and a couple extra characters have been added that I've been meaning to integrate with my wildcard setup).

I spent a little while building this wildcard up, and every character on this list has been tested and can get consistent results across most Illustrious checkpoints that I thought to try.

Note: This is designed to be used with the dynamic prompts extension for A1111 or ComfyUI, and as such there is a variant in one of the entries.
If you are not using something that supports variants, then you might want to remove it from the file. It's on line 35, in the Shadowheart prompt.
