In the image attached, the 1st case represents an equation inside Word equation editor, the 2nd shows the same equation but outside equation editor (select then alt+=), and the 3rd represents what I actually need; the equation outside equation editor preserving the unicodes of the characters.

I have a lot of equations to work on, and I cannot replace the letters with their respective maths unicodes manually. So, is there a way the Word can keep the unicodes even when equation editor is disabled.
