PDF export via LaTeX is broken

[haniibrahim]

First, thank you for sharing your kernel. I use it with the classic Jupyter notebook. When I export a notebook as PDF (via LaTeX) it fails. I tested it on GNU/Linux and macOS. The PDF export works with Python3 or gnuplot kernel on both platforms.

This happens even with simple notebooks. Just with one disp command. I tested it with a couple notebooks.

When I export a notebook as LaTeX only there is a weird character which is also in the error message : ^^H
Refer LaTeX-file at https://hani-ibrahim.de/public/misc/nb.tex, line 390

Error message on GNU/Linux: 500 Internal kernel error

...

! Text line contains an invalid character.

Hi @haniibrahim, I believe this is related to pexpect/pexpect#669 (comment). We haven't had a work around it in metakernel yet.
