Sure. I'm not sure if it's possible to make it easier to reproduce, but for
now the example would require installing TinyTeX (via
tinytex::install_tinytex(), which can be later uninstalled cleanly via
tinytex::uninstall_tinytex() after you finish the investigation). Then run:
system2('fmtutil-sys', '--all')
# or tinytex:::fmtutil() if fmtutil-sys.exe is not on PATH
and TeX Live would throw an error like this:
...\username\AppData\Roaming\TinyTeX\bin\windows\runscript.tlu:864: no
appropriate script or program found: fmtuti~1
The command "fmtutil-sys" is longer than 8 characters and hence shortened
to "fmtutil~1". Yes, in principle, TeX Live should work with short path
names, but it doesn't at the moment. I haven't figured out if it was a
recent breakage in TeX Live or not (I've tried to contact TeX Live
developers).
BTW, shell('fmtutil-sys --all') works fine.
