I cannot reproduce that - a document titled <Strange’s text`s here´s double”s> e.g. shows fine.
You could try to turn off all your plugins to see if the problem goes away.
If there's no problem with the title when you turn off all plugins, then you can turn them on one by one until your menu bar problem shows again, and you'll have found the cause.
If the problem is still there with all plugins off, you could try to create another test-document with a title that is the same, and see if that test-document also result in the same problem (Plugins can run code when posts or pages are saved and the problem would then only occur when saving).
