First seen in a Stack Overflow question, but re-created here for testing purposes. The page title and the header displaying the question title above the question disagree on some character replacements. In my testing this included:
- Many (yes, even more than three) consecutive full-stops get collapsed into one U+2026 Horizontal Ellipsis
- Two dashes get replaced by U+2013 En Dash
- Straight quotes (U+0022) get replaced by “curly” quotes (U+201C and U+201D, respectively)
All these replacements don't happen in the page title, which makes for funny page titles if you actually include, like, 100 full-stops which get collapsed into a single U+2026 on the page itself.
