--- Comment #4 from David <lassi_suri...@yahoo.ca> --- This bug is still valid. I did a fresh install of both Debian 9.5 and Kubuntu 18.04 on the weekend and noticed that KDE still exhibited odd behaviour around dead keys. Depending on exact locale settings, I would have no dead keys, or dead key combinations would insert incorrect characters. However! I was able to solve the problem by modifying certain locale-specific files outside of KDE. I will describe below. In my specific instance: Keyboard: Canadian Multilingual Locale: Esperanto Solution: add the following lines to /usr/share/X11/locale.alias (package libx11-data): eo.UTF-8 eo_XX.UTF-8 eo_XX.UTF-8 eo_XX.UTF-8 eo_EO.UTF-8 eo_EO.UTF-8 add the following lines to /usr/share/i18n/SUPPORTED (package locales): eo ISO-8859-3 eo.UTF-8 UTF-8 eo_XX UTF-8 eo_XX.UTF-8 UTF-8 The above changes make sure that both locales and libx11-data are harmonized in terms of what encodings to use for EO locales. KDE is no longer confused. If other people are having problems with their dead keys in KDE, they should check the encoding definitions in the above 2 files, and, as an extra measure make sure that /etc/default/locale defines a default system locale that uses UTF-8 (in my case system default is now eo.UTF-8). As a concluding note, since the solution for me was outside KDE, this may not be a KDE bug, however it is worth remembering that it is mostly KDE applications (specifically Qt applications) that are affected by mismatched locale definitions, and Gnome and other environments don't seem to have a problem. I hope this is helpful. -- You are receiving this mail because: You are watching all bug changes.
