pdfLaTeX epstopdf converts all text to monotype font

Question

When including .eps files with \includegraphics and compiling with pdfLaTeX, I get all fonts in monotype font even though the original .eps file has another font specified, e.g. Helvetica or Arial. I've tested both Helvetica and Arial (the latter of which is installed on my Windows 10 system) to make sure it wasn't an issue of whether the font is installed.

Here are the two example eps files I'm using to test it:

https://github.com/skhiggins/test_epstopdf/blob/master/sample_eps_arial.eps

https://github.com/skhiggins/test_epstopdf/blob/master/sample_eps_helvetica.eps

Opening the .eps files in a text editor, I confirmed they declare the fonts as Helvetica and Arial, respectively, using e.g. %%DocumentNeededResources: font Arial. If I open the .eps files using gsview they appear correctly. However, when I compile a pdf in LaTeX the font of the graphs is monotype. (If I run epstopdf in the command line, I also get monotype font.) Here is the LaTeX code that I compile with pdflatex.exe:

\documentclass[12pt]{article}
\usepackage{graphicx}
\usepackage{epstopdf}

\begin{document}

\includegraphics[width=\textwidth]{sample_eps_helvetica.eps}
\includegraphics[width=\textwidth]{sample_eps_arial.eps}

\end{document}

Both graphics appear in the pdf as follows, with a monotype font :

I already tried the obvious things like uninstalling and reinstalling MiKTeX. Here is the log:

Answer 1

I had the same problem, I don't know the reason, but the solution for me was to reinstall Miktex to the previous version (basic-miktex-2.9.6850-x64).
