The goal of this project is to provide information about how various pieces of software (e.g. operating systems, DBMS and others) sort textual data, in the form of easy-to-read charts.

The project aims to help developers in writing portable applications which have to deal with linguistic sorting, as well as to migrate between various operating systems and DBMSs more easily.

We'll also be collecting links to other projects aiming to solve migration or portability problems related to linguistic sorting and searching.
