There are several common mistakes that prevent applications from being properly localized. Find out what they are and how to easily avoid them in this tutorial.
Building KDE's Localization Module
Building and installing language support from KDE's localization (l10n) module is a good idea for those working on applications in the main KDE repository. Doing so will allow you to test your application in another language and spot problem areas. Learn how to do just that in this tutorial.
Incorporating i18n Into the Build System
