Hardware: All
OS: All
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org

Unicode text which contains zero width joiners displays differently on macOS and iOS.
To reproduce:
1) Open the following page on both platforms:
https://meta.stackoverflow.com/questions/361390/can-posts-to-stack-overflow-be-fingerprinted-using-hidden-unicode-characters
2) Compare how the code samples are rendered
Expected result:
The rendering should be identical.
Actual result:
The rendering is quite different. iOS appears to be displaying the zero width joiner as a space character.
