Specifically I want to write these in LateX:

enter image description here

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

enter image description here

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

enter image description here

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.

    amssymb provides \digamma – egreg Jun 5 '16 at 22:47

    MinionPro and mathdesign also have a digamma. – Bernard Jun 5 '16 at 23:13

    Please add images rather than links. Not dismissing other people's work quite so blithely is also recommended, but courtesy is not always a requirement for receiving an answer. – cfr Jun 5 '16 at 23:40

    @William I think it would be a lot fairer to say that the more effort is put into a question, and the easier it is to answer it, the faster answers will come and the better they will be. Now, in general, links are especially problematic as people (including me) would rather not follow them, because of security concerns. I don't follow links if I can help it and certainly not to sites I don't know. It's also just nice if questions can be self-contained. What if that link goes dead? Your question is worthless – Au101 Jun 6 '16 at 1:42

    @William Even though you dislike the amssymb version, this is what Digamma looks like. It essentially boils down to finding a font which has a Digamma glyph in your preferred shape, because the Unicode code point it readily available at the link you posted. I suggest you search the web for Unicode math fonts and browse their character table. – Henri Menke Jun 6 '16 at 9:07

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}

enter image description here

  • U+0191 is LATIN CAPITAL LETTER F WITH HOOK; U+03DD is GREEK SMALL LETTER DIGAMMA; U+1D7CB is MATHEMATICAL BOLD SMALL DIGAMMA. There are also U+03DC GREEK LETTER DIGAMMA and U+1D7CA is MATHEMATICAL BOLD CAPITAL DIGAMMA. Curiously, there's no “non bold” variant. – egreg Jun 6 '16 at 9:36
  • @egreg Is there just no non-bold in the font or in Unicode as a whole? – Henri Menke Jun 6 '16 at 11:05

    @HenriMenke only bold mathematical digamma (it was added to support the ISO entity set isogrk4) the non bold entity had already been mapped to U+03dd and getting another character in without the ISO entity backup is (or was) tricky.. – David Carlisle Jun 6 '16 at 11:28
