When I create a file with just one line and one character 0x23de in UTF-8
encoding (i.e., file contents is u"\u23de\n" in Python notation), and I open
this file in Emacs, the buffer is not displayed. Instead, I still see the
*scratch* buffer which was opened before. When moving point in this
(invisible) buffer, I get the following error message: "line-move-1: Arithmetic
error"
In GNU Emacs 23.0.60.3 (x86_64-unknown-linux-gnu)

Do you still still see this error with the latest version of Emacs from
CVS?

I still experience a short freeze when the position with the high
Unicode codepoint is visited for the first time while scrolling
through the file. (Maybe fonts are loaded into memory?) But the
reported bug is gone.
Tschö,
Torsten.
