How to include font into document?
"Font shape undefined" with latex and isodoc
I am using the following in a document:
\usepackage[T1]{fontenc}
\usepackage{calligra}
\usepackage{tgothic}
\usepackage{libertine}
I am using Ubuntu Natty and I am getting the following warning:
LaTeX Font Warning: Some font shapes were not available, defaults substituted.
I must be missing a package but I am not sure which one?
