internationalization

本技能重点覆盖 Unicode（UTF-8、UTF-16）、ICU4C 库、区域设置处理、排序规则、数字/日期格式化，以及 ETS stdlib 的 i18n API。适用于以下场景：(1) 实现国际化功能；(2) 使用 ICU 库；(3) 针对不同区域设置进行格式化；(4) 处理 Unicode 文本；(5) 支持从右向左书写的语言；或 (6) 设计具备区域感知能力的 API。

description: Important skill covering Unicode (UTF-8, UTF-16), ICU4C library, locale handling, collation, number/date formatting, and i18n APIs for ETS stdlib. Use this skill when: (1) Implementing i18n features, (2) Using ICU library, (3) Formatting for locales, (4) Handling Unicode text, (5) Supporting RTL languages, or (6) Designing locale-aware APIs.

Internationalization

Quick Start

Locale-aware formatting:

typescript
// Format number with locale
formatNumber(1234.56, "en_US");  // "1,234.56"
formatNumber(1234.56, "de_DE");  // "1.234,56"

ICU integration:

cpp
// C++ side with ICU
auto formatter = icu::NumberFormat::createInstance(locale);
formatter->format(number, result);

Unicode handling:

  • •UTF-8, UTF-16 encodings
  • •Code points vs graphemes
  • •Normalization (NFC, NFD)

Key Concepts

Unicode:

  • •Code points: Unique numbers
  • •Graphemes: User-perceived characters
  • •Surrogate pairs: Emoji, > 0xFFFF

ICU Library:

  • •Locale handling
  • •Number/currency formatting
  • •Date/time formatting
  • •Collation (sorting)
