What’s happening
We have a group whose Full name is set to “Utah - St. George”. On the group page itself, the name displays correctly. But when the group link is pasted into Slack, the preview shows “Utah - st. george”, with everything after the first letter in lowercase. Looking at the page source, the `og:title` and `twitter:title` tags already contain the lowercase version, so this comes from Discourse and not from Slack.
What I expected
The preview should show the Full name exactly as entered: “Utah - St. George”.
To reproduce: Create a group with a Full name that has capitals after the first letter (e.g. “Utah - St. George”), then view the page source of the group page. The `og:title` and `twitter:title` tags show only the first letter capitalized.
Version: Self-hosted, Discourse v2026.10.0-latest +342.
