Thanks for your replies.

Firstly, at first sight, this bug seems not particularly related to the commat entity but the way the HTML file is read / parse and rendered until this character.

After your comments, I was able to reproduce this bug again on Epiphany Technology Preview WebKitGTK 2.45.92 on Debian 12. I tested it previously on Void Linux (distribution package) and on Linux Mint LMDE (flatpak) and obviously encountered the same error.

To further describe the error, it is written in a red rectangle at the top of the page:

This page contains the following errors:
error on line 2 at column 3176: Entity 'commat' not defined
Below is a rendering of the page up to the first error.

Then, as it is written, the page is rendered below the rectangle until the "problematic" character.

I have uploaded this file to the W3 validator website https://validator.w3.org/#validate_by_upload. I don't see any relevant information about the file being not valid (although you may have a look to confirm my opinion).

The exact steps I took to reproduce the bug are:

- Go to the attachment link with a browser other than Epiphany (In my case Firefox) https://bug-278992-attachments.webkit.org/attachment.cgi?id=472397.
- Right click and select View Page Source.
- CTRL-A and CTRL-C.
- On your system create a file `commat_bug.html` and paste the clipboard content. You should have two lines of code.
- Then save the file: its md5sum is 5a342cce19b976dd612ee044a23159cc.
  If you inadvertently added a new line character at the end, the md5sum is a40ea32795a1466d9b32319506d693ed.
- Open this file with Epiphany. In my case, I open the Thunar file browser, right click on the file and select Open With.

Are you able to get the error by following this steps and with the right checksum?

I'm not sure if this is really "a bug" on Epiphany's part, or if the problem is in the file. Having open it normally in Chromium and Firefox (and from your sides on Safary etc.) suggests to me that something is not normal and there may be an issue somewhere.
