 The package fakes a vector font with outline characters by the text render of PDF.
 It writes directly into the pdf output with \verb|\pdfliteral| (pdflatex ) or \verb|\pdfextension| \verb|literal|

 mode one should use the bold version of the text font which should be available in most cases. This is different to the
 math mode where only some free math fonts provide a bold version.
