i18n? wtf?

@elibelly

Numeronym

A number-based word, for example:

  • Numbers as sounds: K9, l8r

  • numbers as meaning: 411, 007

  • adding up the number of letters between the first and last and then using that number instead of the middle of the word, wow, what a good idea : i18n, l10n, a11y

  • ... n7m

Internationalisation

If you internationalise, you design or develop your content, application, specification, and so on, in a way that ensures it will work well for, or can be easily adapted for, users from any culture, region, or language.

W3C Standards

You might do something like...

🇪🇸

Your web code with templates or placeholders for strings

localised string resources

think about...

  • Language

  • Writing System - é, โลก, 世界

  • Formatting Date, Time, Currency - 01/09/17

  • Writing Direction - RTL, LTR

  • Ordering, Pluralisation - one, few, many

  • Grammar

  • Relative time - 'days ago'

  • Locale

Continuous Localisation

  • ease
  • price
  • services & features

It is a way of automatically, seamlessly gathering new source material, publishing it for translation, acquiring translations and integrating them back into the product.

i18l has a logistics problem

I18n is much easier to integrate into your project early

@elibelly

  • Internationalise all the things - I18n is part of accessibility
  • I18n is supported by a bunch of standards, helps do it "right"
  • Try to start early if you can
  • Always let your user pick their own locale
  • German is a great first test language!

🙏 Thank you 🙏

Internationalisation is a Piece of Cake - BerlinJS

While about 51% of the world’s websites are in English, only about 25% of web users are English speakers. With half of the world’s population online, internationalisation is as relevant as ever! Let’s explore how i18n gets made on the web.
