Unable to post images with certain filenames using Share Sheet from Photos app

Expected behavior

• Uploaded image appears on the blog post.
• <img> tag contains a URL to the site's Media Library.

Actual behavior

• A broken image appears on the blog post.
• <img> tag contains a URL to a local iOS path (e.g. ///private/var/mobile/Containers/Shared/AppGroup/35CF9C30-0B32-4B11-ADC3-C7DDE5E92589/Media/)

Steps to reproduce the behavior

1. Take any standard JPEG or PNG file and rename it with the filename crown-house_©-francesco-russo_websize_002-1-1, keeping the file’s extension.
2. AirDrop it to iOS / iPadOS.
3. In the Photos app, choose the photo and launch the Share Sheet.
4. Use either method in the above screenshots to create a new post or a new draft.
5. Load the new post on the WordPress site and observe that the <img> tag’s src attribute looks something like: ///private/var/mobile/Containers/Shared/AppGroup/35CF9C30-0B32-4B11-ADC3-C7DDE5E92589/Media/image_140f0c50-6547-4f91-946b-6c17e7f7f28f.crown-house_%C2%A9-francesco-russo_websize_002-1-1.jpeg instead of an image located in the site’s Media Library.

Other details

• The photo still landed successfully in the Media Library in my testing.
• I believe this issue is independent of type of site (the customer had Atomic and I’ve tested on self-hosted and Simple).

Tested on iPhone 12 Pro, iOS 14.6, WPiOS 17.6
