Summary

• Renaming attachment to a non-ASCII character before upload causes the room history to not load properly the next time

Environment

• Mac 4.0.4
• Windows 4.0.1626
• Web 3.0.325

Steps to Reproduce

1. Attach a file to the chat (public room / private room / 1-1 chat)
2. Rename the file to any of the non-ASCII symbols included in the attachment non_ascii.txt
3. Press enter and confirm that the uploaded content will not be shown on the history
4. Close the room and reopen it again

Expected Results

Actual Results

• The room / 1-1 conversation history will not load and gets stuck with the following screen shot:
  

Notes

• If you check through the web interface room / 1-1 chat history, you will see the content there. E.g. https://www.hipchat.com/history/member/XXXXXX or https://www.hipchat.com/history/room/XXXXX
• Somehow, the clients cannot display the content due to the non-ASCII character rendering

Workaround

• Continuously enter 75 messages or more so that the content will not be loaded upon entering the room
• Delete the content from the web interface and re-open the room / 1-1 conversation again
