The document discusses internationalization (I18N) and localization (L10N) in Codename One. I18N is the process of making a single application work across different locales, while L10N adapts the application for each specific locale. A locale goes deeper than just language and includes things like number, date, and sentence formatting. The document also covers translation, formatting numbers and dates based on locale, and handling right-to-left languages like Hebrew and Arabic where the entire UI needs to be flipped.

✦I18N - Internationalization the process of making one
app that works everywhere for every “locale”
✦L10N - Localization is the process of adapting to each
locale
✦Locale - unlike language locale goes deeper it’s how we
write our numbers, dates, phrase our sentences etc.

4. Translation

✦Resource bundles installed in UIManager
✦Seamless to code…
✦But can be used manually
✦Missing MessageFormat functionality: This is the {0}
time
✦Cultural translations can be done on top: colors,
images, gender, politics…

16. Formatting

✦L10NManager &

✦Allow formatting dates and numbers based on locale,
currency etc

✦RTL (Right to Left) or BiDi (Bi-directional) represents the
problem posed by some ancient languages (Hebrew,
Arabic etc.)
✦RTL languages are written from right to left but the
numbers within (or english) is written from left to right
(hence bidi)
✦In these languages the entire UI should be flipped or it
will look odd, this includes the alignment of the
elements. Codename One does that implicitly
