[pdfcomment] the font option produces PDFs that only render correctly in Adobe Acrobat, not Poppler (xpdf, evince, okular)

This is the sample code (for LuaTeX or XeTeX):

\documentclass{scrartcl}

\usepackage{pdfcomment}
\usepackage[english]{babel}
%\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{microtype}
\usepackage[svgnames,rgb]{xcolor}
\usepackage[absolute]{textpos}
\usepackage{amssymb,amsmath,array,bm}
\usepackage{courier}
\usepackage{calligra,mathptmx,helvet,concmath}
\usepackage{times}
\usepackage{fontspec} % used to access system fonts like Lucida Fax

\begin{document}

\pdffreetextcomment[avatar=standard,font=calligra]{This font is Calligra}\\[6mm]

\end{document}

The first question is what can be done to make the fonts render correctly in Poppler-based PDF viewers?

The other question: is Poppler the only game in the FOSS town? Or is there a FOSS alternative?
