[BUG] Dashes in session path turns into backslashes

[Lucirukei]

Describe the bug
Having dashes (-) in the project directory name, or any other directory in the project path, breaks loading sessions with the search/picker.
The dashes gets turned into backslashes.
See screenshots for example. I have a repo called test-repo-test, but it shows up as test\repo\test, meaning I can't load it with the picker.

To Reproduce
Steps to reproduce the behavior:

1. Save a session of a project directory with dashes in the name.
2. Use the Autosession search command
3. Try to load the session with dashes, now backslashes, in the name
4. See error

Expected behavior
See the project path as it should be, with dashes in the name rather than backslashes.
Select the project path and have it load.

Screenshots

Baseline (please complete the following information):

• Result of set sessionoptions?:
  sessionoptions=blank,buffers,curdir,folds,help,tabpages,winsize,winpos,terminal,localoptions
• OS. e.g uname -a:
  Windows 10 Pro (22H2) x64
• Neovim version nvim --version
  NVIM v0.9.1
• URL to your current config (if public)
  Not public.
  But I've tested with only Lazy and auto-session installed, and no other settings. Same problem.

I could not reproduce on my OS X Ventura (NVIM version is 0.9.1 too). Seems to be a windows specific bug.
I can later try on my windows laptop and maybe I'll be able to fix it.

Yeah. The reality is I don't really officially support Windows with auto-session. All Windows support has been pretty much added by the community, which is amazing to see! Hopefully someone can dive into this one soon!

Same issue with git, having a dash in a git branch name (I have the auto_session_use_git_branch set to true) results in an incorrect, uselessely unescaped path.

Here the branch name was 54-sandbox.

I don't recall hvaing this issue until really recently tho, but can't find the update that broke it.

#315 improves this case so while it's still converting dashes to backslashes, it will load the session when selected. For example, I have a directory called "dash-test" and the session file is rendered as "dash\test":

Selecting it does load it successfully:

@rmagatti what about url encoding the filename of the session? Then we could use the same encoding scheme on all platforms and have it be fully reversible while only being slightly more cumbersome to look at via ls (which shouldn't be an issue for an end user anyway)?

[cameronr]

Actually, now that I think about it, I wonder if it's possible to make it work by being careful/consistent with how paths are treated. I'll look into this a bit more.

[rmagatti]

Urlencode would be good, I do remember considering that at the time but don't quite remember why I didn't go with that. Perhaps there wasn't a good option to do that in Lua with Neovim at the time or something like that

@rmagatti I think this can be closed now
