Math & Science ⇒ mathdesign's Bitstream Charter and amsmath

[Montag]

Hello,

when using any version (in terms of order) of the following commands

Code: Select all

\usepackage{amsmath,amssymb}
\usepackage[bitstream-charter]{mathdesign}
%\usepackage[defaultsans]{lato}

I get:

Warning: Package 'amssymb' shouldn't be used in conjunction with package mdbch, on input line 20.

This warning appears two times for the same line, which is where \befin{document} is written. Yet the document seems fine, especially the embedded fonts in the pdf-file (viewable via CTRL+D in AR).

I looked for it online, and I couldn't find any good answer, except some hints.
Is it ok to ignore the warning, or should I do something about it?

Are you sure you need to load amssymb if you're using mathdesign? Mathdesign claims to provide support already for all the AMS symbols, so perhaps it would already define everything you need? So I'd keep amsmath (first), drop amssymb, and leave the rest as is.

But that said, I doubt there will be a problem to use them both together, or else you would have noticed it already in the output.

... sure, that was a stupid error on my account, thank you.
