[Tex/LaTex] How to write this Digamma Symbol in Latex

Question

Specifically I want to write these in LateX:

Unicode name: Mathematical bold small digamma
Codepoint (hexadecimal): 0x1D7CB
Codepoint (decimal): 120779
In unicode block: Mathematical Alphanumeric Symbols

Unicode name: Greek small letter digamma
Codepoint (hexadecimal): 0x03DD
Codepoint (decimal): 989
In unicode block: Greek and Coptic

Unicode name: Latin capital letter f with hook
Codepoint (hexadecimal): 0x0191
Codepoint (decimal): 401
In unicode block: Latin Extended-B

I am using TeXstudio, so I can compile in pdflatex, xelatex, or lualatex and some other ones.

What is the simplest possible way to do this? I don't care about the nitty-gritties of how various compilers work — I just want a simple command and the environment in which that command gives the desired output.

Free Serif has your desired glyph.

\documentclass{article}
\usepackage{fontspec}
\newfontface\DejaVuSans{DejaVu Sans}
\newfontface\FreeSerif{Free Serif}
\def\Fhook{\mbox{\DejaVuSans\char"0191}}
\def\digamma{\mbox{\DejaVuSans\char"03DD}}
\def\mbfdigamma{\mbox{\FreeSerif\char"1D7CB}}
\begin{document}
\Fhook \digamma \mbfdigamma

$\Fhook \digamma \mbfdigamma$
\end{document}
