What tools and techniques are supported for developing multilingual programs?

Developing multilingual programs typically involves tools and techniques such as internationalization (i18n) and localization (l10n) frameworks, which facilitate the adaptation of software for various languages and regions. Popular libraries and frameworks like GNU gettext, Angular's i18n support, and React Intl help manage translations and cultural nuances. Additionally, translation management systems (TMS) like Transifex or Crowdin streamline the workflow for translating and updating content. Version control and continuous integration tools are also essential for maintaining consistency across different language versions.
