[screen-devel] Fwd: Bug#882340: screen: please update wcwidth/Unicode data [origin: address@hidden

[Axel Beckert]

Hi,

this patch has been submitted to Debian with the request to forward it
to upstream which I hereby do.

While I generally trust the submitter as well consider him competent
with regards to charset and especially Unicode encodings, I've not
much of an idea what the patch actually changes and I'm very reluctant
to update defacto binary code which I don't really understand and
which is not cryptographically signed.

I assume one of the upstream devs is more comptent than me with that
matter and able to review the patch and hopefully include it in the
screen-v4 as well as the master branch.

(If preferred, I can also open a ticket on Savannah for this.)

                Regards, Axel

Package: screen
Version: 4.6.2-1wtf1
Severity: normal
Tags: upstream patch

Please apply the attached patch, and forward it upstream, to bring
Unicode (wcwidth) data up to date with latest glibc master.

Symptom:

Download the following file and edit it in screen in an 110x24 uxterm:
http://mirsolutions.de/music/free/Haydn%20--%20Die%20Himmel%20erz%c3%a4hlen%20die%20Ehre%20Gottes.mscx

The status line (first line of the terminal) in the jupp editor is
corrupted because GNU screen, in the version in Debian, mistakenly
handles the line width wrong.

In an 80x24 uxterm with screen, this does not happen because the
fancy WTF-8 characters in question are close to the end of the
line in the file and thus only displayed when the terminal is
wide enough.
