These need to be converted into equivalent UTF-8 sequences to look right. I wish to emphasize that libc6 is the *only* package which does this. Seems logical, see below. If the bug is not in package libc6, then why is libc6 the *only* package which doesn't use the proper box-drawing technique? Because your UTF-8 locale isn't available at the time the above screen is shown. It comes from the libc6 preinst, and libc6 declares a Breaks on the old locales package (see #585737 for details). Sorry for the long delay in responding, Sven. I just now noticed your update to the bug log. I get hundreds of e-mails per day. I must have accidentally deleted yours before reading it. I will try running apt-get install locales first from now on, before running apt-get upgrade or apt-get --purge dist-upgrade, and see if that helps. -- .''`.

Bug#754596: libc6 package upgrade sends ISO-2022 escape sequences to a terminal which doesn't support them (PuTTY in UTF-8 mode)
. It's only when using a terminal which does *not* support ISO-2022 escape sequences in UTF-8 mode that we have a problem. Personally, I believe that supporting ISO-2022 escape sequences in UTF-8 mode represents a standards violation (see http://www.cl.cam.ac.uk/~mgk25/unicode.html#term). But that's beside the point. The point is that PuTTY does *not* support ISO-2022 escape sequences in UTF-8 mode, and due to the terminal type definition of xterm-utf8, ncurses knows this. Yet it is being sent untranslated ISO-2022 escape sequences somehow. But only when upgrading package libc6. Not when upgrading any other package. Very strange. -- .''`.

Bug#597756: iconv: conversion stopped due to problem in writing the output
Package: eglibc Version: 2.11.2-5 I'm not sure if this bug is in iconv itself or in another package which calls iconv, but since I have discovered the problem in at least two packages (bash and dash) I will report it against iconv and you may reassign it as you see fit. When looking at the man page for bash or dash, then quitting immediately on the first screen by pressing q, I sometimes get the following error message: iconv: conversion stopped due to problem in writing the output But I can't seem to reproduce the problem consistently. Sometimes I get the error, and sometimes I don't. I have yet to come up with a scenario that always causes the failure symptoms. -- .''`.
