Collation + i18n support in musl libc

musl libc is a lean C standard library implementation for Linux. It strongly focuses on correctness, compliance with standards, and reduced footprint, both in terms of binary size and memory usage. Its initial release dates to 2011, making it a considerably modern implementation compared to alternatives like glibc. As default in e.g. Alpine Linux (which is widely used in containers but also is the basis for end user facing efforts like postmarketOS) it can be found in many unexpected places.

This project will implement two features still missing: collation and internationalization support. The first one allows set ordering based on locales, and follows a certain set of established rules and standards. The second one provides basic functionality in the language of choice for the user like dates, times, numbers, and monetary symbols. Contributors from the postmarketOS community will validate the work, to make sure that everything actually works out as intended.
