I would be much more confortable if this only turned on by default in buffers where we _know_ that's ok, such as *help* buffers, info buffers, and maybe Emacs sources. What bothers me is that it'll happen on any buffer without confirmation or notification. Let's say the user is reading some code designed to read a stream and do something with quotation marks. Or maybe the user is reading prose in a context where typography is important. Usually they'll have a font to display these round quotations, but if they start emacs without a graphical frame for one reason or another (or, god forbid, they've misconfigured something) then it would a problem that they see " when they actually have =E2=80=9C or =E2=80=9D. Now, those are not very likely scenarios, that's why it bothers me a little less if it's just quotation marks. But I wanted to make sure we're aware of this, specially if this feature starts spreading to other characters. > Not really: the display engine doesn't examine any of those > characters, until they are on or very near to the visible portion of > the buffer. Yeah, I see how that would be complicated. I guess I'll just step down from soap box now.
