\begin{fontthemeexample*}{professionalfonts}

- This font theme does not really change any fonts. Rather, it \emph{suppresses} certain internal replacements performed by \beamer. If you use ``professional fonts'' (fonts that you buy and that come with a complete set of every symbol in all modes), you do not want \beamer\ to meddle with the fonts you use. \beamer\ normally replaces certain character glyphs in mathematical text by more appropriate versions. For example, \beamer\ will normally replace glyphs such that the italic characters from the main font are used for variables in mathematical text. If your professional font package takes care of this already, \beamer's meddling should be switched off. Note that \beamer's substitution is automatically turned off if one of the following packages is loaded: |arevmath|, |hvmath|, |lucidabr|, |lucimatx|, |mathpmnt|, |mathpple|, |mathtime|, |mtpro|, and |mtpro2|. If your favorite professional font package is not among these, use the |professionalfont| option (and write us an email, so that the package can be added).
