Discussion:
Disappearing unicode in Literate Agda - XeLatex
(too old to reply)

I've been trying to get literate agda up and running as per the
instructions in the documentation
<https://agda.readthedocs.io/en/v2.5.3/tools/generating-latex.html>
and I'm having problems getting unicode symbols to appear inside code
blocks. I've run "agda --latex code.lagda" to get the following
"code.tex" file below .



\documentclass{article}



\usepackage{agda}



\begin{document}



ℕ



\begin{code}%

%

\>[4]\AgdaKeyword{data}\AgdaSpace{}%

\AgdaDatatype{ℕ}\AgdaSpace{}%

\AgdaSymbol{:}\AgdaSpace{}%

\AgdaPrimitiveType{Set}\AgdaSpace{}%

\AgdaKeyword{where}\<%

\end{code}



\end{document}

When I compile it using XeLatex (or LuaLatex) everything compiles without
errors and it all appears fine (including the first ℕ symbol outside of the
code block) except that the ℕ symbol inside the \AgdaDatatype{} command
doesn't appear. The same problem occurs when I place any unicode character
inside the \AgdaDatatype{} command. I've tried adding in various
combinations of the following package imports (even though according to the
documentation they shouldn't be necessary in XeLatex):

\usepackage{bbm}

\usepackage[greek,english]{babel}

\usepackage{ucs}

\usepackage[utf8x]{inputenc}

\usepackage{autofe}

Does anyone have any suggestions?

Thanks,
Matthew

Agda, XeLaTeX and LuaLaTeX versions?

Also attach `code.lagda` please.

This is a known problem:

LaTeX backend + XeLaTeX/LuaLaTeX ⇒ no lambda
https://github.com/agda/agda/issues/2225

I assume that the output from XeLaTeX includes something like the
following:

Missing character: There is no ℕ in font cmss10!

This can be handled in different ways. I've used newunicodechar, but
this solution does not play well together with microtype, which is used
by acmart. For my latest paper I decided to use pdfLaTeX instead. (I
used \DeclareUnicodeCharacter, and gave the nofontsetup and
noinputencodingsetup options to agda.sty.)

Thank you very much for the link to the issue. I'm only trying to typeset a
small amount so the \newunicodechar workaround is fine for now. It might be
worth splicing it into the documentation as it seems it's been open for a
while.

I am getting slightly different symptoms as I'm getting no errors at all in
the log, so there is no

Missing character: There is no ℕ in font cmss10!

error appearing. My code.lagda file is as follows:

\documentclass{article}

\usepackage{agda}


\begin{document}


\begin{code}

data ℕ : Set where

\end{code}


\end{document}


And my code.tex is file is:


\documentclass{article}

\usepackage{agda}

\begin{document}

\begin{code}%

%

\>[4]\AgdaKeyword{data}\AgdaSpace{}%

\AgdaDatatype{λ}\AgdaSpace{}%

\AgdaSymbol{:}\AgdaSpace{}%

\AgdaPrimitiveType{Set}\AgdaSpace{}%

\AgdaKeyword{where}\<%

\end{code}


\end{document}


My tex version is:

XeTeX 3.14159265-2.6-0.99992 (TeX Live 2015/Debian)
kpathsea version 6.2.1
