This is not only a ITF-8 issue. I'm surprised TeX Live is said not to work properly out of the box on some Linux distributions, hard to believe it's true.
My conclusion from earlier discussions is that it is a challenge to configure fonts to a given user document. It may contain (besides latin-1) Greek, Cyrillic, CJK, emoji. While browsers and office tries hard to find some substitution if a requested font does not have a set of glyphs, for LaTeX it is necessary to explicitly configure fonts for every script. For PdfTeX it is even more tricky than for LuaTeX. In some cases fonts installed system-wide and ones available for TeX engines are not the same.
Some Org users are not familiar with TeX, so configuring fonts is a really difficult task for them. (On the other hand they do not need perfectly formatted document.)
I do not mind that accessibility is important, but a year or two ago its status in LaTeX was "in progress". Is it necessary to modify LaTeX markup generated by org-export? Can it cause issues with older TeXLive versions from stable/long time support Linux distributions?
P.S. In some cases it may be easier to get PDF from ODT or HTML intermediate format.
