Overview

Format description: developer.apple.com/library/mac/documentation/macosx/conceptual/bpinternational/Articles/StringsFiles.html

Example: /* Insert Element menu item */ “Insert Element” = “Insert Element”; “Windows must have at least %d columns and %d rows.” = “Les fenêtres doivent être composes au minimum de %d colonnes et %d lignes.”; “File %@ not found.” = “Le fichier %@ n’existe pas.”; “%@ Error! %@ failed!” = “%2$@ blah blah, %1$@ blah!”; “File "%@" cannot be opened” = “ … ”;

Localizable.strings is a default filename. It is recommended that you save strings files using the UTF-16 encoding.

Use /usr/bin/plutil -lint (part of Mac OS X) to check for syntax errors.
