Exported PDF should use the same Font and Bullet list styles as in view mode

XWiki exported PDF file looks too different to source wiki page. In particular, the differences between the exported PDF and the original wiki pages are in font-family, bullet list style, and table style (table headings, border, etc.), at least that's for the case I tested. To compare, XWiki Print Preview function, browser's print preview function, print-to-PDF operation (through a PDF printer e.g. the free PrimoPDF) all produce very close-to-the-source output.
To work around this issue, one solution could be to customize one of the style-sheets related to the PDF export process, as described here: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Configuration#HCustomizingthePDFexportLook26Feel but most users probably just prefer good (looks like the source) result out of the box.
