`[[--opt]]` typesets to `-opt` (drops one dash) with T1 font encoding

[dbosk]

See -edit and --edit:

The code for the image:

The course responsible must then generate the sign-up sheet.
This is done by running the following command.
\begin{minted}{bash}
nytid signupsheets generate prg[im]24 --edit
\end{minted}
The [[--edit]] option opens the generated sign-up sheet (or sheets in our case, 

Not sure this is expected, I kind of expect [[...]] to be close to verbatim (exception being chunk names) considering I quote code with it.

I can add that it's the same in code chunks, not just quoted code.

<<script.sh>>=
cmd --arg
@

Here --arg would also be typeset as -arg.

>> (when not part of a chunk) is typeset as », but > is typeset as >. Not sure if that's intended. I would be fine with » if > would be more similar. (I'm writing shell scripts at the moment.)

I can't duplicate the fault.

Sorry for that, experimented a bit. Here is a MWE, test.nw:

\documentclass{article}
\usepackage[utf8]{inputenc}
%\usepackage[T1]{fontenc}
\usepackage{noweb}

\begin{document}
This is a test to see how [[--opt]] is typeset.
<<script.sh>>=
echo "Hello, world!" >> /tmp/hello.txt
echo --opt
@
\end{document}

Weaved using noweave -delay test.nw > test.tex && pdflatex test.tex.

Got it down to the fontenc package. Whenever the fontenc line is uncommented, the problem occurs.

I use \usepackage[T1]{fontenc} to get the Swedish letters å, ä, ö correct in PDFs (when selecting and copying them from the PDF they're actually the letters, without T1 you can't copy the text).

Added But how is >> now, and > >? before \end{document}:

[dbosk]

But in maths \(a > b\) works?:

Did some more experiments.

Seems like I don't need \usepackage[T1]{fontenc} anymore for Swedish. So I can just remove that line and solve my problem. (See below.)

If I use xelatex instead, everything just works:

\documentclass{article}
\usepackage{noweb}

\begin{document}
This is a test to see how [[--opt]] is typeset.
<<script.sh>>=
echo "Hello, world!" >> /tmp/hello.txt
echo --opt
@

But how is >> now, and > >?
But in maths \(a > b\) works?

What about å, ä and ö?
\end{document}

Weave using noweave -delay test.nw > test.tex && xelatex test.tex produces

Turns out I need the T1 font encoding for other things. (I used other fonts in my original document.)

XeLaTeX didn't help here. Gives the same horrible font as in the top example, just without the upside-down symbols. But still the guillemets for >>. Works with XeLaTeX after setting fonts correctly.

[dbosk]

The only issue I encounter with XeLaTeX is that I can't use [[...]] in section headings. Might be due to the fonts. I'll continue experimenting.

If you are using Unicode, XeLaTeX is definitely the way to go.
