Math & Science ⇒ unicode-math | Use with LuaLaTeX

[anddm]

Hi to you all guys!

I'm using LuaLaTeX and I'm experiencing some troubles with the unicode-math package. The editor I'm using is TeXmaker.

I have something to propose to you. Any help will be really appreciated! The questions are:

1. declaring \setmathfont, the package will set all needed for typesetting maths, from symbols to letters. It will also define math alphabets such as \mathcal, \mathfrack, \mathbbit, and so on.
   
   The question is: how to define new math alphabet, i.e. math alphabets not included in \setmathfont? Something else then \mathbbit, maybe something like \mathbbbf, that is bold upright blackboard, perhaps. I was tempted of using the primitive \DeclareMathAlphabet, but I do not
   know how to use it with fontspec!
2. as said earlier, \setmathfont set also Greek letters, lower case and upper case. How to modify these ranges? For example I just want to use XTIS Math's Latin
   alphabet but with Asana Math's capital Greek letters.
   I can't do that using only the declaration \setmathfont[range=Greek]{Asana-Math.otf} because otherwise it will take so much time as the developers themselves have admitted.
3. how to get the package mnsymbol working with unicode-math without any issue of compatibility at all?
   I mean that when I'm using the packages unicode-math and mnsynbol together the following compilation error comes up:

   Code: Select all

   ! LaTeX Error: Command `\sqrtsign' already defined.

   As a matter of fact, it isn't the only one. There are five of them and among of these there is also \widehat.

Thank you so much in advances!

Best regards,
