`\s` is not encoded properly, breaks further fromJSON()

[nkbt]

It could be purely transit-js issue, will move to upstream if not the problem of transit-immutable-js

My JSON after encoding looks like this:

[
  "^ ",
  "componentRouter",
  [
    "^ ",
    "pathname",
    "/ddos",
    "hash",
    null,
    "query",
    [
      "^ ",
      "filters",
      "blabla\sqwer"
    ],
    "cleanQuery",
    [
      "^ ",
      "^4",
      "blabla\sqwer"
    ],
    "defaultParams",
    [
      "^ "
    ],
    "routes",
    [
      "^ ",
      "/ddos",
      [
        "^ ",
        "route",
        "/ddos",
        "regex",
        "~^/ddos$",
        "params",
        [
          "^ "
        ]
      ]
    ],
    "currentRoute",
    [
      "^ ",
      "^9",
      "/ddos",
      "^:",
      "~^/ddos$",
      "^;",
      [
        "^ "
      ]
    ],
    "locationType",
    "LOCATION_HISTORY"
  ]
]

Some context: this is universal JS app, I serialize Redux store on a server (partially immutable-js, partially plain objects) and then I am trying to deserialize it in a browser. Accidentally my route had something\something in it, and that \s broke fromJSON() because backslash was not escaped.

Expected value:

[
  "^ ",
  "componentRouter",
  "...cut",
  [
    "query",
    [
      "^ ",
      "filters",
      "blabla\\sqwer"
    ],
    "cleanQuery",
    [
      "^ ",
      "^4",
      "blabla\\sqwer"
    ]
  ],
  "...cut"
]

\b is ok for some reason. But other combinations like \a, \c fail too.

I checked with transit-immutable-js glenjamin/transit-immutable-js#20 and it seems like upstream bug, so opening here.

[glenjamin]

Are you able to reproduce with a smaller example?

[nkbt]

I removed all reducers except one for routing. It had only plain js objects. Same issue persists when I have backslash in the url.

Not something urgent here for me.
Mostly checking if anyone else had similar issue.

Ps: I am leaving roday for holidays otherwise would definitely Investigate further and PR. Well, will do when I'm back if nothing comes up

[glenjamin]

I had a go at this using just transit, I can't seem to get it to produce a \s.

Can you provide some sample code that passes an object and results in a broken string?

[nkbt]

Must be related to #23 too.
