# Font shape undefined despite using either or both of fix-cm and lmodern

My document begins:

``````\RequirePackage{fix-cm}
\RequirePackage[l2tabu, orthodox]{nag}
\documentclass[oneside]{memoir}  % TODO 12pt
``````

Nevertheless, I get errors:

``````LaTeX Font Info:    Font shape `OMS/cmr/m/n' in size <10> not available
(Font)              Font shape `OMS/cmsy/m/n' tried instead on input line 139.
``````

How do I fix these?

Looking closely at the document, these are caused by something in the itemize environment (the bullet symbol?), the copyright symbol, and something in my bibliography.

It's not an error. Please, add some lines that produce the warning. –  egreg Jul 2 '12 at 20:57
@egreg: updated the question. Is there a way to suppress these errors? –  Neil G Jul 2 '12 at 21:05

The warning is completely innocuous and is typically generated the first time an `itemize` environment is used. There are two ways to avoid it:

``````\usepackage[T1]{fontenc}
``````

or

``````\usepackage{textcomp}
``````

Note that `fix-cm` is not needed when `lmodern` is used as its works is made useless by later loading a completely different font family.
The choice between `fix-cm` and `lmodern` is up to your personal tastes. Computer Modern and Latin Modern fonts are very similar anyway. –  egreg Jul 2 '12 at 21:10
@NeilG: I would recommend `lmodern`. –  Mico Jul 2 '12 at 21:11
@NeilG: The `lmodern` package comes with a lot more glyphs than does `cmodern` (whether or not the latter is "fixed up" by loading `fix-cm` as well). The additional complement of glyphs is, admittedly, not important if you use mainly English and have little need for accented characters. –  Mico Jul 2 '12 at 21:15
