[Aptitude-devel] Bug#950334: aptitude: Help -> User's Manual contains special characters

[Bruno Kleinert]

Package: aptitude
Version: 0.8.12-1
Severity: minor
Tags: l10n

Hi,

aptitude displays unwanted special characters in the user's manual view in a
German environment (I didn't test if the same happens with different locales).

To reproduce, I use the following locale environment:

fuddl at wurst:~$ locale
LANG=de_DE.UTF-8
LANGUAGE=
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

Start aptitude in an 80×24 characters terminal, select Hilfe (Help) -> Handbuch
(User's Manual) and press page down once. You should see an output as in the
left terminal window in the attached screenshot.

The terminal on the right of the screenshot is for reference and shows aptitude
with environment LANG=C. With that environment, aptitude displays the user's
manual correctly.

The special characters make the manual difficult to read, especially tables in
the manual.

Cheers

Bruno
