UTF-8 related display problem

[Marc Wilhelm Küster]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195)
 of 2002-10-01 on LAPTOP1
configured using `configure --with-msvc (12.00)'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: DEU
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Opening a largish UTF-8-encoded text file (ca. 800 kb) with Latin, Greek 
and Hebrew passages in it causes emacs to stop displaying the text about 
halfway through the text. It is impossible to navigate beyond that break.
Shortening or lengthening the text does only move slighlty the point where 
the text display stops.

The break seems always to be in non-Latin text.

The file displays without problem in other UTF-8-aware applications, so the 
UTF-8 itself should be correct.

Choice of font does not have any effect on this behaviour.

Best regards,

Marc Küster
