Both the Evince and PDF Tools AUCTeX viewers already support that
provided that SyncTeX would return a sensible column number which it
sadly doesn't.

I've looked at it and didn't understand it.  But even if I did, that
wouldn't help us because we need to use the information provided by the
viewer.  And that's (file line column) where column is always -1.

See above.  And I'm pretty sure that both Evince and PDF Tools query the
synctex info from the PDF.

So my guess is that either TeXStudio hacked up SyncTeX to supply correct
column numbers, or they use a dirty trick like their previewer returns
not only the line information but also the word at click position which
they then can search after jumping to the right line.

Well, in both cases, we're out of luck since we cannot (nor want to)
provide a better SyncTeX, nor are we able to change what viewers like
Evince supply when backward searching.
