Two special characters

Question

I would like to write the two special characters for Medieval Latin transcriptions of "per" and "pro" (see the attached image). Does anybody know if those characters exist? I do not find them. Thanks!

Welcome to TeX.SX! The two symbols ꝑ and ꝓ are found in the Latin Extended-D Unicode block. In particular, Ꝑ (U+A750), ꝑ (U+A751), Ꝓ (U+A752) and ꝓ (U+A753).

Regarding input, a Unicode compile engine is recommended: XeTeX or LuaTeX. Regarding output, you need to choose a typeface/font that supports Latin Extended-D. You can choose Symbola, Quivira or any other fonts you find suitable (see also the MUFI font page). Make sure to read the font license!!

% !TeX program = XeLaTeX
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Symbola_Hinted.ttf}
\begin{document}
per/par: ꝑ: emꝑere (emperere), ꝑler (parler)

pro: ꝓ: ꝓmis (promis), ꝓdome (prodome)
\end{document}
