Unbelivable!! That's not a practical format for humans to express in written form!! I think that's a step backwards from Egyptian hieroglyphics. C'mon in 2016, with an advanced staged of technology and have to write with that I think is plain retarded, undoing centuries of evolution. Whover came up with that standard should be fired for causing brain damage and waste of CPU cycles.

Specially with UTF-8 which it could take advantage of the many features it got.

I just found out that "alt+6+numbers" works in the system:

¹a²b³c⁴d⁵e⁶

But I can't find the letters. So the font is installed already. I'd love to be able to do this with letters.

thanks.
