A few months ago I was using Lout to produce Postscript (.ps) files, Evince or Atril to view them, and happily making progress. Then I got distracted with other things, upgraded my Arch machine, and now when I view the .ps files, all math symbols are missing. I suspect something with the postscript viewers or font files or config data related to either is missing something. It appears that only glyphs in Symbols are missing. Dingbat shows okay, and regular body text looks fine.
When I view one of the files I made a while ago, those math symbols are missing, though the file looked fine last summer.
I was using Lout 3.40 from an external tarball, but switched to Arch's package to see if it made a difference. Nope. Still not seeing math symbols.
I heard from someone who had trouble like this after a ghostscript upgrade. A downgrade fixed it.

I've never come across or used Lout (it looks old given that it was last updated on 2013-07-15 according to https://www.archlinux.org/packages/comm … 6_64/lout/ ), but I'd think that font substitution is no longer working for you for your .ps files. I suppose that's one good reason to convert ps files to pdf files as fonts are embedded within a pdf.
Have you had a look through the fonts page on the wiki - https://wiki.archlinux.org/index.php/Fonts - perhaps you are missing some fonts? Perhaps also think about moving to an alternative?

Example from a math paper I'm writing. It's so close to being done!
https://imagebin.ca/v/3pOzS0TFEvub screen capture of part of page five, viewed in Atril.
Below: Postscript code from the file roughly corresponding to this snippet - I hope this looks correct to Postscript experts. If it's correct, then it's Evince/Atril/etc not finding or using certain fonts correctly. Butif this PS code is messed up, I need to investigate why Lout isn't doing what it used to do right only a few months ago.

I don't know if this is relevant, but looks suspicious on its own. When I run 'gs' with no params, and at the GS> prompt enter 'loadallfonts', I get a zillion messages looking like:
Substituting font Times-Roman for Hershey-Plain-Duplex.
Can't find (or can't open) font file hritrb.gsf.
Can't find (or can't open) font file /usr/share/ghostscript/9.22/Resource/Font/Hershey-Gothic-Italian-Bold.
Can't find (or can't open) font file Hershey-Gothic-Italian-Bold.
Didn't find this font on the system!
When I look in /usr/share/ghostcript/9.22/Resource/, there's no Font directory.
I find some .pfa files and .otf files in /usr/share/fonts/gsfonts/ and under /usr/share/groff/ (but I don't think groff has any relevance at all here) There's no misplaced 'Font' directory in /usr/share or /usr/local.

When I look in /usr/share/ghostcript/9.22/Resource/, there's no Font directory.
I have a /usr/share/ghostscript/9.22/Resource/Font directory and it currently contains 37 files. Perhaps reinstall ghostscript?

I'll try a re-install. Most times when I use pacman for more than just installing one thing, there are packages it asks me about replacing with other packages, or removing. I usually take the defaults. If pacman then decides not to install anything, I answer those questions differently. It may have been some situation like that, where some font or other files critical to Evince, Poppler, ghostscript or something they depend on, got replaced but not completely/correctly.

Aha, 'pacman -R evince atril poppler ...' followed by 'pacman -S ..." seems to have fixed the immediate problem.
I had to remove more than just evince, atril, poppler, ghostview and a few related things. A bunch of apps depend on those, and not wanting to wrestle with pacman, I removed them and will re-install them later. Now I might have an inconsistent system, and should do a proper 'pacman -Syu' soon, but not now.
Also, I now see the /usr/share/ghostscript/9.22/Resource/Font directory. It's a mystery why it disappeared.

Glad you are sorted - sooner rather than later I'd say for the -Syu ! Be careful of doing partial upgrades and don't forget to prepend [solved] to your first post...
