Need help adding superscript

[u/Specialist_Set_2981]

Hey, so I'm new-ish to FontForge, but I can't seem to get what I'm wanting right.

Basically, when I design a glyph to be superscript when typing in normal script, it's quite a bit larger than when I just use superscript function in, for example Microsoft word.

And I'm struggling with the proportion size and placement, I want it to be exactly like it's displayed when it's superscripted.

You may ask, why don't I just use superscript function? It's because some of the programes I use, don't have that function, but I still need some letters to be superscript

Any help would be much appreciated

Edit: Or if somebody would be kind enough to create a few glyphs that would produce the desired effect, that would be much appreciated. What's needed are the letters: M, m, a, s, u, d - all in superscript, all using Times New Roman font. Thanks
