# pstricks package preventing compilation [closed]

Today I updated to the latest version of MiKTeX (2.9.6703, I was previously using an older version of MiKTeX 2.9) and now the pstricks package entirely prevents me from compiling a document when loaded using \usepackage{pstricks}. Thus, the code below produces fatal error messages, but commenting out \usepackage{pstricks} means the document compiles just fine.

\documentclass[a4paper,12pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage[UKenglish]{babel}
\usepackage{libertine}
\usepackage{pstricks}
\begin{document}
Hello world!
\end{document}


I get 100 identical error messages saying:

! Text line contains an invalid character. l.1 ...@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@ ^^@^^@^^@^^@^^@^^@^^@^^@^^...

I get the same errors whether I use XeLaTeX, LuaLaTeX of pdfLaTeX.

Does anyone have any idea what's going on?

(Edit: This question was originally about pst-asr but it seems the problem is actually with pstricks, on which pst-asr is dependent.)

• This document compiles fine with XeLaTeX or latex + dvips. It won't compile properly with pdfLaTeX or LuaLaTeX although it shouldn't produce the error you show. I'm using TL2018. Try deleting the .aux files and recompiling with XeLaTeX. – Alan Munn May 27 '18 at 21:04
• they are byte 0, ascii NULL so you have a corrupted file but it is impossible to say from the small fragment of log shown which file is bad – David Carlisle May 27 '18 at 21:42
• Thanks! It looks like my installation of iftex was corrupted; un- and reinstalling has got rid of the error. – Miztli May 27 '18 at 22:00
