# No -8bit with xelatex

I wanted to use verbatim with beamer document class, but I noticed that all the tabs are replaced by ^^I.

A solution has been given to this problem Tabs in output file written by xelatex and pdflatex are different

But to solution requires that -8bit is added on the command line of xelatex. If I try to do that, I get the following error in xelatex.log:

``````2017-05-24 14:26:10,919+0200 INFO  xelatex - starting with command line: xelatex -8bit document.tex
2017-05-24 14:26:10,927+0200 FATAL xelatex - The command line options could not be processed.

So where did -8bit go and is there an alternative?

• Welcome to TeX.SX! The `-8bit` option is valid for the TeX Live implementation of XeTeX; why this isn't accepted by MiKTeX is beyond my understanding. – egreg May 24 '17 at 13:03

XeTeX 3.14159265-2.6-0.99992 (MiKTeX 2.9) uses option `--enable-8bit-chars` instead of `-8bit`.

• I use version Version 3.14159265-2.6-0.99998 (MiKTeX 2.9.6300 64-bit), which is slightly newer, and --enable-8bit-chars still don't work with xelatex, but does work with pdflatex – Michiel Fortuin Aug 8 '17 at 7:52
