The installer has layout issues. The EN messages contain line break at a particular position to break to a new line because the layout component do not resize according to the text width. Sine the translated messages will have the line break at a different position, the text in the localized installer UIs are truncated. We manually fixed this issue in 3.1.1. it is a very tedious process for new releases. We would like this issue to be fixed in 3.1.2 because new translations will be done for this release.
