For the PDF in question, that displays numerous entries, showing Helvetica, Helvetica Bold, Helvetica BoldOblique, Helvetica Oblique and two entries displaying: [none]
The Helvetica entries show Type 1, no embedding. The two [none] entries show Type 3, embedded. fonts-liberation and fonts-liberation2 are already installed.
Helvetica isn't a Microsoft font. It's a sans-serif commonly seen on Macs. The usual Microsoft replacement is Arial, but I don't think it's 100% metrically identical, so Liberation Sans wouldn't be either.
Of course, it's possible that the Helvetica fonts aren't actually used anywhere in the document and that the two nameless fonts are derivatives of something else altogether. That would be far from the stupidest thing I've ever seen anyone do with a PDF file.
What is occurring, was that the layout of the PDF viewed with any of the aforementioned packages (except Vivaldi), wasn't 100% perfect. For example, spacing between the letters was uneven.
That suggests a kerning problem, and possibly an unsuitable font substitution. You may want to dig into your distro's information on fontconfig. The command "fc-match Helvetica" can be used to see what your system's substitute for Helvetica is.
It's also possible the designer was a bonehead and adjusted the spacing between letters without embedding the font. That's . . . a little more difficult to fix.
