When attempting to flag a post (or any replies within it) for the reason “Other,” the system generates a private message to moderators. If the original post’s title contains an emoji, the action fails with this error:
This appears to be caused by the fact that PMs to moderators inherit the post’s title, and the PM system disallows emojis in titles.
This is a critical issue as it prevents users from flagging certain posts or their replies for “Other,” which is often required to provide detailed context to moderators. Without this ability, moderators may lack sufficient information to make informed decisions on how to handle flagged content.
Reproduction Steps:
- Find or create a post with an emoji in the title.
- Attempt to flag the post itself or any reply under it.
- Select “Other” as the reason.
- Click “Submit.”
- Observe the error message: An error occurred: Title can’t have emoji.
Expected Behavior:
Flagging for “Other” should work regardless of whether the post title contains emojis. The system should either strip emojis from the PM title automatically or handle them without error.
