Hi everyone, <br><br>When I compile my document,  xelatex has been returning  me  lots of warnings such as the one below: <br><br><br>&quot;Package polyglossia Warning:  brazil@font is not defined on input line XXX&quot;. <br>
<br>Documents compile fine, but don&#39;t have a clue what all those warnings are all about, or why they appear at all. <br><br>Here&#39;s my preamble: <br><br>\documentclass[12pt, oneside]{scrbook} <br>\usepackage{scrpage2} <br>
