[Bug]: Having a "#" character in the prompt causes a file not found exception

[Zyin055]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What happened?

Using a prompt that has a "#" causes the completed image to not be displayed in the image gallery. It throws a RuntimeError: File at path C:\Stuff\AI\Stable Diffusion\outputs\txt2img-images\22352-8- does not exist.

It appears that the "#" is acting like a python comment, cutting off the rest of the file name.

The file exists in my hard drive, and I can view it normally through file explorer using IrfanView.

Note that using a "#" before I updated to this version that supports SD2.0 worked a few weeks ago. That working commit was: c5334fc56b3d44976425da2e6d0a303ae96836a1. I know this because I used to use "#" as a placeholder for the X/Y Prompt S/R script.

Tested with SD2.0 model and older models.

Steps to reproduce the problem

1. Type any prompt with a #, such as "a # beautiful woman"
2. Press Generate button
3. After generation completes, an image not found icon is displayed where the image preview should be

What should have happened?

Image preview should be shown in the image gallery instead of an image not found icon.

Not sure why the issue name was changed since this occurs without any script running. I don't believe the X/Y script is causing it - it was just an example use case for using the # character.

[ClashSAN]

sure, change it, it had no title before

Oh, I must have forgot to enter one. My bad

I've got the same issue by trying the prompts from Aesthetic Gradients:
https://github.com/vicgalle/stable-diffusion-aesthetic-gradients

Tried in UI (quotes for clarity):
"Roman city on top of a ridge, sci-fi illustration by Greg Rutkowski #sci-fi detailed vivid colors gothic concept illustration by James Gurney and Zdzislaw Beksiński vivid vivid colorsg concept illustration colorful interior"

gives:
raise RuntimeError(f"File at path {self.path} does not exist.")

I read in another thread that "round brackets are from Stable Diffusion" and "curly brackets are from NovelAI"
Is that similar case for # symbol in prompts?

What does # do in NovelAI?
