Description David Kaspar [Dee'Kej] 2015-10-21 09:13:56 EDT
+++ This bug was initially created as a clone of Bug #717367 +++

Description of problem:
tcsh has some troubles with printing sequences of wide (eg. 'ö') and single-byte ASCII characters (eg. 'a') using LANG=C.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Set LANG=C
2. Start tcsh
3. Type a wide character (eg. 'ö')
4. Type any single-byte ASCII character (eg. 'a')
Actual results:
The single character is printed 6 times instead of just once. For example when "öa" is typed, "aaaaaa" is printed.

Expected results:
The single character shall be printed just once, as expected.

Additional info:
The bug was revealed in bug 676305 comment 5.

Comment 2 David Kaspar [Dee'Kej] 2016-03-31 06:56:35 EDT
For some reason I have cloned this BZ by a mistake. This issue is not present in current TCSH release, this has been already fixed in TCSH 6.17.03 (current base for RHEL7 is TCSH 6.18.01).

List of changes between 6.17.00 and 6.17.03:

Commit fixing the issue:
(You can easily lookup in the fist link that it is part of it.)

I have also tested the behaviour and it is correct:
~ export LANG=C
~ ./tcsh
$ (writing ö character)
$ \303\266
