Looks like inputenc is incomplete then - the correct action then
is to fix inputenc.

Nothing IMHO, since this problem is not new. In the long run mathed should probably use some mechanism similar to the unicodesymbols file to replace unicode characters with appropriate commands, and then it could also replace ° with a command that works always. It might be possible that this would already work with the lib/symbols file, but I am not sure if you can put single characters in there and only redefine the LaTeX output. Georg

a _correct_ and save way is to do nothing inside LyX and using
always the LaTeX definitions. In fact of some compatibility
you can do inside LyX
\providecommand\LyXtextdegree{\ensuremath{^\circ}}
\let\textdegree\LyXtextdegree
and using \LyXtextdegree _always_ in math mode.
all other cases cannot be handled in a save way, because the user
can load packages in his own order, packages which redefine this
setting, ...
However, using the gensymb package with its \degree-Symbol is
the best choice.

sure, nobody did such a \DeclareTextCommand. But it is really easy
to do it yourself. This has nothing to do with inputenc as package.

Re: Major problem with \textdegree
I thought I'd re-use this thread. Hit C-m, "\circ", on my system I get red writing "circ" which is basically what I would get if I typed anything else with a backslash. But the generated output has a circle. Something missing from my system? I think when this happened in the distant past it was related to missing fonts that the X-server didn't know how to find. It's not very good behaviour because I was trying to figure out why something I remembered from 4 years ago wasn't recognised. I think the correct behaviour for a missing font is to emphasise it somehow so I know it's going to be recognised by LaTeX at least. Have fun, Darren

But then lyx2lyx will have to translate the textdegrees to text mode. No. This part of lib/symbols is only used for display, so removing the hack does not cause a fileformat change. The problem is really that both a literal ° and \textdegree work with latin1 encoding _in mathed_. They don't work with latin9 encoding. So the hack in lib/symbols only reflects the fact that \textdegree sometimes works even in mathed, but it does not cause any harm. Don't ask me why the inputenc package does what it does, I don't understand it, I only see the results. This does also mean that at the time when the language encoding of some languages was changed to latin9 there should have been a lyx2lyx change, because old documents with encoding setting auto and ° in math or text will not work anymore.

Sure, \textdegree does not depend on the inputenc package.
What does not work with \usepackage[latin9]{inputenc} (in TeXlive 2005) is
a literal °. It does work with latin1. And this is stupid, because ° is
contained in the latin9 encoding at the same position as in latin1: 0xb0.

\usepackage[latin9]{inputenc}
\usepackage{textcomp} %<---
\usepackage{babel}
\begin{document}

text: °

Even if ° would not request textcomp, there's always the possibility that some
other package does.

Now I know what the problem is. $\textdegree$ works in 1.4 (and also in 1.5)
because it is defined in lib/symbols:
\def\textdegree{\kern-1mu^{\circ}\kern-4mu}
However, as soon as the package textcomp is loaded, this definition will be
overridden by textcomps definition, which does only work in text mode.
Now in the test file, there's an additional unicode symbol °, which requests
unicode. Delete that symbol, and the math \textdegree will show up.
I'm not sure yet what we can do about it.

The inputenc package is stupid. The latin9 encoding does contain the degree

No. With ERT you are allowed to shoot yourself in the foot, both in normal

I meant automatically replace \textdegree with \mbox{\textdegree}

Major problem with \textdegree
Hello,
There's some problems with \textdegree reported on the users list that I
can easily reproduce. With the attached LyX file, the LateX export will
translate the degree symbol in mathed to \textdegree.
Neither the dvi nor the pdf (pdflatex) file shows the \textdegree symnol
but both of them shows the unicode symbol just fine.
Bernd Sellentin (message reproduced below) suggests to put
\usepackage[latin1]{inputenc} in the preamble. But this leads to a LateX
error about a clash in the inputenc package.
This is a major bug IMHO, LateX expert someone?
Abdel.
Hi,
studying the Latex error messages, I noticed that lyx-1.4 sets the
inputencoding to latin1. This works for textdegree. lyx-1.5 sets it to
latin9, this does not work for textdegree.
On my debian system are both encodings installed:
[EMAIL PROTECTED]:~$ locale -a|grep de
de_DE
[EMAIL PROTECTED]
de_DE.iso88591
[EMAIL PROTECTED]
de_DE.utf8
deutsch
In the preferences dialog I found no possibility to tell lyx, which
encoding
to use. My workaround: put the "Use language's default encoding" off and
put
in the latex preamble \usepackage[latin1]{inputenc}.
Now textdegree works, and as I am writing text about chemistry with a
lot of
textdegree symbols I have only one change to do to make my scripts working
again with this very nice lyx-1.5.
