Is there a way to vertically align two Texts letter by letter

I have an TMPro input field which takes 5 letters. Under it, I have a TMPro Text Field uGUI element. Both have equal font sizes and character spacing settings. Alignment is also identical. However, the letters don’t align to the underlines. I understand (I think) that this depends on the letters but I was wondering if these could be aligned to have exactly equal spacing so each letter is always exactly above an underline?
Thanks

EDIT: Found the solution, to use monospacing with the <mspace=1.2em> (example) tag
