If you want languages with more interesting shaping, you have to start compositing glyphs; but good shapers are out there. HarfBuzz is amazing, I'm always amazed how well random bits of Farsi and Mongolian typeset on my systems.
Not sure about Unity, but it helps to be able to submit the geometry, the shader, and the uniforms, then asynchronously (or if you're lucky, in another thread) submit the SDF after you're done computing it.
