(NOTE! Not all of the symbols are accurate. I went through all of the symbols supported in Segoe UI, in Microsoft Word. Some symbols either don't show up right, or aren't even included in the font itself. If you have a replacement for a symbol, feel free to comment below. I may update the list with your symbol in it. I'll credit you for finding it, to be fair.

Oo: ⚐⬚ (Yes I know the lowercase o is supposed to be a box but look below)
Pp: 🚩⬜ (I used the normal box for lowercase p since the thick box doesn't work)
