This document discusses the relationship between language, culture, and software. It covers several key points: 1) Language and culture are closely intertwined, with language representing the dominant sign of any given culture. Different languages reflect different worldviews. 2) Cultural variables like date formats, number formatting, and colors must be taken into account for software to be successfully localized for other cultures. Internationalization involves developing a cultural model and using international variables. 3) Localization requires adapting aspects of software like graphics, text directionality, and shortcuts to be appropriate for a given language and culture. This helps ensure software usability and understanding across cultures.
