How would I typeset Jean-Yves Girards fu and wo in TeX? Or maybe there are some Unicodes for it?

1Do you mean the Japanese scripts? There are Japanese fonts around, those are Katakana. – Skillmon May 21 '19 at 14:02

Unicode calls them KATAKANA LETTER HU (U+30D5) and WO (U+30F2). – egreg May 21 '19 at 14:32

The glyphs are KATAKANA LETTER HU (U+30D5) and WO (U+30F2).
I prepared the following file (except
\documentclass{article}
\usepackage{CJKutf8}
\pagestyle{empty}
\begin{document}
\begin{CJK*}{UTF8}{gbsn}
フヲ
\end{CJK*}
\showoutput
\end{document}
Running LaTeX, I got, on the console,
....\hbox(0.0+0.0)x15.0
....\C70/gbsn/m/n/10/30 ?
....\kern -0.00002
....\kern 0.00002
....\glue 0.0 plus 0.96002
....\C70/gbsn/m/n/10/30 ?
so I modified the file to have
\documentclass{article}
\usepackage{CJKutf8}
\pagestyle{empty}
\begin{document}
\begin{CJK*}{UTF8}{gbsn}
フヲ
\end{CJK*}
% this has been added after examining the result of \showoutput
\texttt{\expandafter\meaning\csname C70/gbsn/m/n/10/30\endcsname}
\showoutput
\end{document}
Now the PDF file tells us the font is gbsnu30. With the help of the fonttable package, I see that the relevant characters are in slots "D5 and "F2 (as expected from their code points in Unicode).
OK, we have what we need.
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\DeclareFontFamily{U}{katakana}{}
\DeclareFontShape{U}{katakana}{m}{n}{ <-> gbsnu30 } {}
\DeclareRobustCommand{\fu}{\text{\usefont{U}{katakana}{m}{n}\symbol{"D5}}}
\DeclareRobustCommand{\wo}{\text{\usefont{U}{katakana}{m}{n}\symbol{"F2}}}
\begin{document}
\noindent
Et sourtout, la forme suggère de nouvelles opérations : ainsi le deux
constantes logiques $\fu$ (\emph{fu}) et $\wo$ (\emph{wo}) sont-elles
issues de considerations morphologiques, sans le moindre substrat
sémantique. Puisque $\fu={\sim}\fu$, on obtient même une réfutation
\emph{logique} de la logique classique.
\[
\fu,\quad \wo_{\fu\wo}
\]
\end{document}

An example using the CJKutf8.sty package working with pdfLaTeX and XeLaTeX:
\documentclass[]{article}
\usepackage{CJKutf8}
\newcommand*\fu{\begin{CJK}{UTF8}{ipxm}\Unicode{"30}{"D5}\end{CJK}}
\newcommand*\wo{\begin{CJK}{UTF8}{ipxm}\Unicode{"30}{"F2}\end{CJK}}
\begin{document}
text \fu\ (fu) and \wo\ (wo)
\end{document}
