Hello,

Long time ago I tested Esenthel, but considered do not use, because my project requires a lot of render text to textures, runtime materials/shaders creation. Also mobile rendering level was a problem (very limited). Was something changed since 2014 ?

Hope to stick to Esenthel...

Hello,

I recommend using built-in text rendering functions, it's very powerful, and flexible, supports auto-scaling, or can be setup for per-pixel drawing if you need to.

At the moment you need to use Source Code License to play around with custom shader creation (it's not easy at the moment).

I don't know what you mean by mobile rendering is limited exactly, but yes, OpenGL ES used on mobiles platforms does not allow for all features.
Here you can see what's supported and what not:

You can try the demo version and check it out for yourself:
