In order to view the text, you need the font Xerxes (TTF, 9KB). This is probably the first publicly available standard font for OldΒ Persian. (The license is GPL with the extra embedding allowed in documents exception.)
Intersting note: Apparently Pango knows how to break the text as can be seen from pasting the text into gedit. The backslash-like characters are Old Persian spaces and thus line breaks are allowed after them, which Pango knows about. But Firefox doesnβt and treats the text as one long word.
