Babel 25.11

2025-07-13

Babel is the multilingual framework to localize documents. It fully supports pdfLaTeX and the Unicode engines LuaLaTeX and XeLaTeX. A few languages even work with Plain formats.

Its aim is to provide a localization framework for different languages, scripts, and cultures based on the latest advances in Unicode (including the CLDR, Common Language Repository Data), the W3C (where applicable) and other technologies, as well as on international standards.

Babel supports approximately from 170 to 300 languages, depending on the engine (with various levels of coverage), across about 45 scripts, including complex and RTL ones. Its high-level interface with fontscpec allows for seamless integration with OpenType technologies in LuaLaTeX and XeLaTeX, enabling the use of advanced typographic features.

The latest stable version is available on https://ctan.org/pkg/babel.
