#2395 "Unable to update the static FcBlanks:" messages from fontconfig and xetex

[U_Fischer]

Since the last update running fc-cache or a small xelatex document like this

\documentclass[]{article} 
\usepackage{fontspec}
\begin{document}
MWE 
\end{document}

leads to a number of messages in the terminal

~~~~~~

I suspect that the <blank> settings in fonts.conf.in / fonts.conf is reponsable as the newest fontconfig no longer accept this entries. See e.g. http://comments.gmane.org/gmane.comp.fonts.fontconfig/5495 and https://github.com/behdad/fontconfig/blob/master/fonts.conf.in

(I couldn't test what happens if one remove this section as I don't know how to recreate fonts.conf after a change of fonts.conf.in.)

This has been fixed.
