Some JSON literal strings unmarshall as nil

this may look like a dumb thing to do - it is actually part of https://github.com/json-schema-org/JSON-Schema-Test-Suite - a testsuite for JSON validators - but I expect that there are quite innocent strings that might elicit the same behaviour from transit.

I would like to use transit but can't because many of the testcases in the above project do not unmarshall correctly...

hmmm... when rendered via markup the string causing the issue gets corrupted - to see the original string, click edit...

here is the json doc surrounded by backticks to hopefully render it literally:

"[{\"data\":\"^(abc]\"}]"

[JulesGosnell]

that is quoted for use in a repl - unquoted it looks like this:

"data": "^(abc]"

transit/read is meant only to read JSON produced by transit/write. It is not meant to consume arbritrary JSON.

If you want to read a JSON string use (js/JSON.parse the-string) which will give you a JS Object. Which you can work with via interop, or turn it into a CLJS structure via (js->clj that-result).
