Please note the discussion at the end of this thread. After discussing the tex codes \ldots et al, a commenter points out that there is a unicode code point for an ellipsis.
However, on my document (which I'm editing in Lyx), the … character prints out in my pdf as something resembling a \cdots code; that is, vertically centered (and in my case, also shifted horizontally to collide with the next word after the whitespace). See the graphic:

In the pdf file itself, I can copy the ellipsis out, and when I paste it into another document, it remains an ellipsis.
This is undesireable behavior; how do I tell TeX to treat the unicode ellipsis correctly as a baseline ellipsis character, and format it accordingly?
ETA: here is an mwe, which isolates the problem:
\documentclass{article}
\usepackage{xeCJK}
\newfontfamily\zhcn [Path=/usr/share/fonts/arphicfonts/]{uming}
\begin{document}
blah … ... blah
\end{document}
On my system, that outputs the ellipsis character as raised and shifted rightwards. If I drop those two lines from the preamble, the text is correctly formatted. But the xeCJK package shouldn't be called unless I specifically flag something to use it, right?
