When I add the package \usepackage{fouriernc} to my document, I begin
getting the string of encoding warnings listed at the end of this
message. I don't get these warnings if I use CM fonts or txfonts
instead.

Can someone tell me why I'm getting this and/or how to "fix" my
setup so they don't occur?

Here's a minimal example:

\documentclass[10pt]{article}

\usepackage{fouriernc}

\begin{document}

\section{Introduction}

This is a font encoding test minimal example.

   It's not error messages, it's just warning messages. Maybe it would
be better that LaTeX displays Info messages for that.

   You can't easily stop these messages. They are displayed by the LaTeX
core. If you want absolutely the silent, you can try:

\documentclass[10pt]{article}
\makeatletter
\let\@font@warningori\@font@warning
\newcommand\shutup{\def\@font@warning##1{}}
\newcommand\youcanspeak{\let\@font@warning\@font@warningori}

Thanks for the "cover-up" fix, Jean-Come, but perhaps it would be
better to know why it's breaking?

The problem is that nothing is breaking :-)

As I said, these messages are not error messages, they are just info
messages (though they are displayed as warning messages).

fourier changes the math encoding for some math alphabets in some math
versions. That's all.

When a half-dozen extraneous messages reach my eyes, something is
broken. The computer exists to serve man, not vice-versa.

Then would it not be preferable to change the fourier encodings so that
this doesn't happen?

By the way, after about a hundred thousand lines of code, I am aware
of the difference between a warning and an error, and despite your
numerous admonitions on the issue, I have not ever referred to it as
an error.

That's just semantics. The thing is, that package (and others) use
LaTeX's built-in methods to provide maths support. When this part of
LaTeX was written, I guess it was considered sufficiently rare that
this would happen that the user would like to know about it.

That's a solution that doesn't really make sense, if you think about
it. In my package that deals with similar things, I make the
redefinitions locally (similar to Jean-Côme's), but the best thing to
do would be to patch the LaTeX kernel, which is a possibility since
this change wouldn't break any previous code. (Or it shouldn't, at
least.)

I'm motivated enough to submit a bug report, so we'll see how it goes.

Hi Will,

I admit ignorance on the issues you and Jean-Come speak. Even so, it
is difficult to understand why hundreds (thousands?) of other fonts
have no such messages, and yet it is necessary or convenient that
these do.

It is also simply a pain to deal with sifting through the
"non-serious" messages each and every time I run LaTeX in order to
find the "serious" ones. I'm sure you both can understand that.

The difference here is that the maths fonts are changing too.
There aren't so many packages that do that...

Definitely, I dislike it too and I've seen it be a point of confusion
for ages now (seemingly).
I hope to file the bug report tonight, unless Morten's listening and
would like to add his 0.02 Euro :)

Aren't the math fonts simply another set of font files (.tfms)? And
isn't the "problem" that LaTeX expects one encoding but these fonts
use another encoding? If those two conjectures are true, then I don't
understand why you wouldn't simply re-encode the fourier math fonts to
give LaTeX what it wants.

Without looking too deeply into what exactly fourier is doing, and
presuming that the fourier designer(s) would have used the standard
encoding if they could, I surmise that the reason they use a different
encoding is because they provide different/more characters than those
provided by Knuth's fonts. So it wouldn't be a lossless conversion with
respect to what you could obtain from the fourier fonts.

To re-iterate, it's not because fourier is using another encoding when
LaTeX expects something else, it's that the package changes what
encoding is used for various fonts. The problem is that LaTeX is rather
verbose about when this happens, needlessly, and if you like
overloading the meaning of the word "warning".

Cheers,
Will

That's because they use a different math encoding, the default math
encoding and fonts have already been oaded earlier, and they are
substituted at this point. I know of no method to prevent the
earlier loading of the default (cmm) fonts, which would be needed to
quiet down the warning messages; but I have to admit that I have
also not investigated it in more detail. Maybe I ask Frank when I
see him the next time, if one can stop this somehow.

If you use fouriernc please note that it scales down New Century
Schoolbook to have the same x-height as the Fourier math fonts, and
not the other way round. (That's in t1fnc.fd and ts1fnc.fd.) YMMV
how that looks when math is embedded in normal text.

When I commissioned the LaTeX support for these fonts from Micheal,
I couldn't convince him that it might be a better idea to scale the
math fonts up, he foresaw problems with line thickness at fractions
and such. Well, even though he couldn't convince me concerning these
problems, he was the author and so it's scaling text fonts down and
not math fonts up.

Just FYI,

        Joachim

Perhaps \RequirePackage{fouriernc} *before* \documentclass? I haven't
specifically checked whether this quells the warning messages (I set up
my editor to stop flagging them before I started using this method), but
I have frequently used this construction with fourier.sty in order to
set certain dimensions that would otherwise be based on CM metrics. I
admit I have no idea whether it works by *preventing* the loading of CM
in the first place or by simply loading a new font *after* CM but
*prior* to the class declarations, but I suppose it would need to be the
former in order to stop the warnings. The fact that I occasionally have
a CM glyph slip into a document suggests that CM certainly is (or can
be) loaded at *some* point, even with \RequirePackage before \documentclass.

Just a thought.
