I'm trying to import some diagrams I made using Tikz into Inkscape. However, whilst the text displays fine, the symbols seem to change when they are converted into the SVG. Most notably, '-' turns into '<=', among others. I've attached an example below.
I figured it was likely the fonts, but I've made sure to download all the computer modern fonts, and looking at the embedded fonts in the pdf (CMMI10, CMMI7, CMR7, CMSY7), I definitely have all of them -- so I have no idea why they aren't rendering correctly.
I've attached a minimal example:
\documentclass[preview]{standalone}
\begin{document}
$z^\theta_{t-1}$
\end{document}
The correct rendering in texmaker:
Incorrect in Inkscape:


pdflatexin Ubuntu it works fine, even though I don't have the CM fonts installed (Inkscape substitutes with the default sans serif font, which apparently has the theta character and the correct-). You could also try one of the methods at https://superuser.com/questions/315270/generating-svg-from-latex-tikz or https://tex.stackexchange.com/questions/51757/how-can-i-use-tikz-to-make-standalone-svg-graphics or maybe https://stackoverflow.com/a/22407621/. – Marijn Apr 01 '19 at 09:56
