Bug#902299: konsole: UTF-8 broken when having non-default KDE locale settings

[Bastiaan Welmers <haasje@welmers.net>]

Package: konsole
Version: 4:16.12.0-4
Severity: important
Tags: l10n

Since recently, it turned out that UTF-8 did not work properly anymore in Konsole. When opening a UTF-8 file in vim for example, all ocurrences of ö where shown as ö. When entering these kind of characters, they are even saved wrongly. Setting the terminal encoding fixed to UTF-8 via the profile settings did not resolve this issue.

My Debian-wide system locale is set to en_US.UTF8

After some investigation this bug seemed to be triggered by changes made in KDE's System Settings, Reginal Settings, Formats, changed the Region from Default "United States - American English (en_US)" to "Nederland - Nederlands (nl_NL)" since I wanted to use the number/date/currency/paper/unit formats of the Netherlands.
Setting it back to default "No change" and re-login and the problem in konsole is gone.
