I can't figure out why LaTeX won't let me use the 𝔽 symbol (U+1D53D, mathematical double-stuck capital F). When I try, I get the error Package inputenc Error: Unicode char \u8:𝔽 not set up for use with LaTeX.
The input file is UTF-8 encoded. Here is a minimal working (or rather, non-working) example to demonstrate the issue.
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{mathtools}
\begin{document}
% \newcommand{\eff}[1]{F\text{#1}}
\newcommand{\eff}[1]{𝔽\text{#1}}
$ \eff{some} $
\end{document}
When using the first variant of \eff
, everything works (the output is rendered as "Fsome" with an italic F, just as expected). However, if I comment that one out and instead uncomment the second variant, I get the error on line 8 (where I actually use the freshly defined command).
I'm using pdfLaTeX 3.1415926-1.40.10-2.2 from and on Debian Squeeze (package texlive-latex-base version 2009-11+squeeze1) with no special options at all (just pdflatex mwe.tex
) to try to render the document.
I find it hard to believe that nobody would have wanted to use this particular symbol in a LaTeX document, so surely it can be done. What am I missing?

worked perfectly, thank you! If you make that an answer, I'll accept it.
