<Shift> + 4 has resulted in the ¤ character on Nordic XKB keyboard layouts for quite some time. If new keyboards tend to have the € character printed on that key instead, there may be a reason to reconsider it.
However, in any case this won't be changed in Ubuntu only. I would suggest that you file an upstream bug report too. https://bugs.freedesktop.org/buglist.cgi?product=xkeyboard-config If you do, please post the URL to the upstream bug in a comment here. Let me add: Using <AltGr> + E is not a workaround. It's currently *the* natural way to type the € character with the keyboard layout - Finnish (Macintosh), identical with Swedish (Macintosh) btw - you are using. (To make it a bit extra complicated: The currency of Sweden is not Euro.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xkeyboard-config in Ubuntu. https://bugs.launchpad.net/bugs/1785387 Title: Euro sign not working on keyboard (Macbook) Status in xkeyboard-config package in Ubuntu: Confirmed Bug description: https://askubuntu.com/q/1059447/21005 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xfce4-settings 4.12.0-2ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-29.31~16.04.1-generic 4.15.18 Uname: Linux 4.15.0-29-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.1-0ubuntu2.18 Architecture: amd64 CurrentDesktop: XFCE Date: Sat Aug 4 13:18:18 2018 EcryptfsInUse: Yes InstallationDate: Installed on 2017-01-05 (575 days ago) InstallationMedia: Xubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) SourcePackage: xfce4-settings UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xkeyboard-config/+bug/1785387/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
