Howto add math symbol to MathJax

[dei...@gmail.com]

Hi, I need to render symbol rotated True - http://unicode-table.com/en/#22A8 (like http://unicode-table.com/en/#2568) in formulae.
Is it possible to add it somehow or must I modify font and generate it via e.g. https://github.com/fred-wang/MathJax-dev

Thanks in advance

I've successfully generated modified version of MathJax (with https://groups.google.com/forum/#!topic/mathjax-users/e3WBdTXemxw),
But I don't know how to map the new character with e.g. \something
Would you please help me?
TIA.
