-         - Styling effects like bold, italic, text color, text alignment, font size or font switching.
-         - The text may inlude arbitrary languages -- **including right-to-left** languages.
-         - Scripts like `Devanagari <https://en.wikipedia.org/wiki/Devanagari>`_ and several others in Asia have a highly complex system of ligatures, where two or more unicodes together yield one glyph. The Story uses the software package `HarfBuzz <https://harfbuzz.github.io/>`_ , to deal with these things and produce correct output.
-         - One can also **include images** via HTML tag `<img>` -- the Story will take care of the appropriate layout. This is an alternative option to insert images, compared to :meth:`Page.insert_image`.
-         - HTML tables (tag `<table>`) may be included in the text and will be handled appropriately.
-         - Links are automatically generated when present.

       :arg str,Story text: the text to be written. Can contain plain text and HTML tags with styling instructions. Alternatively, a :ref:`Story` object may be specified (in which case the internal Story generation step will be omitted). A Story must have been generated with all required styling and Archive information.
