I found that the problem is caused by this name.

SQUARED CJK UNIFIED IDEOGRAPH-89E3

The Lisp reader reads both "89e3" and "89E3" as 89000.0, but
symbols of those names are printed differently:

(format "%S %S" '\89e3 '\89E3)
=> "\\89e3 89E3"

(1) "89E3" should be read as a symbol.
  OR
(2) '\89E3 should be printed as \89E3.

I'm not sure which is better.

Anyway, I've just committed uni-name.el that contains
"\89e3" (instead of "89e3"), so the current bug should be
fixed now.

The fix for (1) is this:

Stefan and Yidong, please install whichever you think better.
