Translating the strings does not make an application
international.
Dates, numbers, addresses, names, sorting, layout, and persistence
all carry assumptions. Some of those assumptions sit far below the
visible text.
/carbon-intl assesses internationalization readiness
against the locales and markets you intend to support. It is the
engineering investigation beneath the localized experience.
Look for assumptions
that cross layers
Suppose a price is formatted for one locale, parsed by a second
convention, and saved using a third. The interface may look localized
while the stored amount is wrong.
Or a form accepts Unicode names but an export strips them. Or the
date component localizes its display while the validation message still
assumes month-first input.
CARBON can inspect string externalization, locale handling,
formatting, Unicode, right-to-left support, and the relevant test and
delivery setup. Runtime evidence, where available, helps separate actual
behavior from architectural readiness.
Name the intended locales
/carbon-intl assess readiness for German, Japanese, and Arabic; focus on dates, amounts, names, RTL, and export consistency
The report should show a requirements matrix, implementation gaps,
observed results, and the work still needed. It should not declare every
market supported because the framework includes a locale library.
Contextual translation meaning belongs in a localization review.
Internationalization asks whether the product can carry that meaning and
behavior correctly through its architecture.
Finding these assumptions before translation begins can save a lot of
rework. A language file is the visible part of a much larger engineering
decision.
