short answer is NO
There was an attempt to define character position “%c” along the line but was never working/developed and left at a high default value. (Syctex primarily works on blocks of text, hence sometimes does not “highlight” the expected line)
The Synctex standard has since been expanded to include word “hinting” which some editors had developed either independently or now incorporate and thus use. I see Tinn_R only very recently documented the long time pdf syncing so wonder which format they historically use.
They also include stable 2016 SumatraPDF.exe 3.1.2 in their repo and the latest daily SumatraPDF still uses the same legacy methodology since “if it works don’t fix it”.
The prime (only) current developer is not a LaTeX user, so development would need to be done by someone who understands the many ways that Synctex word search might fail.
