This is a test suite for text rendering engines. It is not easy to correctly display text, so we founded this project to help implementations to get this right. With --engine=FreeStack, the tests are run on the free/libre open-source text rendering stack with FreeType, HarfBuzz, FriBidi, and Raqm. These libraries are used by Linux, Android, ChromeOS, and many other systems. — Test report for FreeStack.
