Forward Search doe not work for files located in WSL

[hethon]

SumatraPDF version

• Version 3.5.2

Project structure(files are on wsl)

project_root
├── build
│   └── index
│       ├── index.pdf
│       └── index.synctex.gz
└── src
    └── index.tex

To Reproduce
Execute this from project root.

/mnt/c/Users/Lenovo/AppData/Local/SumatraPDF/SumatraPDF.exe \
-reuse-instance 'build\index\index.pdf' \
-forward-search 'src\index.tex' 42

(Windows handles conversion to UNC paths automatically.)

PDF opens normally, forward search fails with:

Unknown Source file (\\wsl.localhost\Ubuntu\home\hethon\Documents\personal\resume\src\index.tex)

Expected behavior
SumatraPDF should jump to line 42 in index.tex and highlight it.

AFAIK TeX.synctex was designed for use per platform thus one of Mac or Linux or Dos (now Windows) Though each at first had different Distros

Thus an auxiliary file built on one platform was "generally" not expected to work on another, as all use different filesystems (even traditional TEXT suffered from 3 different EOLs)

The synctex system in such cases should always work with the basic TeX rule, i.e. 3 files in same folder don't need to consider the OS as then they are OS agnostic.

But the key point is any stored paths must be basic readable as if in the device used to compile, thus even relative paths ought to be avoided.

With a simple set of 3 files showing identical times (TeX may be oldest by a few seconds) in a single folder they should work.
