Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 127 Stack Exchange communities.

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:

  1. Many (yes, even more than three) consecutive full-stops get collapsed into one U+2026 Horizontal Ellipsis
  2. Two dashes get replaced by U+2013 En Dash
  3. 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.

I added the es...I wanted to see if it only truncated periods or other characters. –  Thomas Owens Oct 30 '09 at 15:06
    
Well, I wouldn't think that multiple instances of e are problematic. Converting 3 or more full stops into an ellipsis makes sense in some way. –  Јοеу Oct 30 '09 at 15:11
    
True. But I was curious. –  Thomas Owens Oct 30 '09 at 15:13
    
WTF? Come on, if you must edit the question title, then at least don't describe a completely different problem. –  Јοеу Nov 1 '09 at 1:19

Not all browsers can render "special" characters in page titles, so we stick with ASCII there.

(for example, some browsers will even render actual HTML in the title, such as <b> and so on)

Don't post questions with titles containing 100 consecutive full-stops.

Doesn't address the underlying problem that some replacement logic here operates only on question titles within the page and not in the page title. The bunch of full-stops was just what caught my attention. It's not something I do regularly. –  Јοеу Nov 1 '09 at 1:20
