Hello, I have run into a bug when using HarfBuzz and dvilualatex. When the following document is compiled with dvilualatex ``` \documentclass{minimal} \usepackage{fontspec} \setmainfont[Renderer = OpenType]{OpenSans-Regular.ttf } \begin{document} Hello \end{document} ``` The produced DVI file cannot be handled by dvipdfmx. Running dvipdfmx produces the following error: ``` dvipdfmx:fatal: Unable to find TFM file "[OpenSans-Regular.ttf]:mode=harf;shaper=ot;script=latn;language=dflt;+tlig;". ``` Removing '[Render = OpenType]' and running dvipdfmx on the resulting dvi file works fine. -- Zameer Manji
