Confluence Quirks

When speaking about page migrations failing, I mean the things on this page. All those tripped up page migration at some point, those are now known and worked around by WikiTraccs (where possible).

This list is more like a “fun” documentation of things, I never thought could happen.

• page with empty title; how is that even possible?
• duplicate attachments:
  
• attachment name that looks like a path; can’t be downloaded:
  
• attachments that differ only by Unicode Normalization Form; names look the same, but are differently encoded; depending on the application that handles those files, they are treated as duplicate - or not
• attachments that are listed in the attachment list, but are missing when trying to download them
• attachments that are listed in the attachment list, but give an error when trying to download them:
  
  • note that in above case the image preview for this image was missing as well, but clicking this “broken image” placeholder did show the image:
    
• attachments names with special characters that are valid on Linux, but not on Windows
• attachment file sizes reported by Confluence are wrong

This list will be extended as more quirks are uncovered.
