Hello ;)
It seems that Emacs' `json-parse-buffer' cannot correctly parse strings
that contain an escaped ascii 0 value.
To reproduce:
- Create a new buffer, insert into it:
{ "foo": "this is a string including a literal \u0000" }
- Move point to the beginning of the buffer [ M-< ]
- Execute `json-parse-buffer' [ M-: (json-parse-buffer) ]
- See the error message.
According to all other systems I've tried, \u0000 is valid in json
strings.
The error message seems to imply that something (probably libjanson?)
should be compiled with -DJSON_ALLOW_NUL.
As this seems to be non-conformant behaviour, is there a way to change
this in the default Emacs build?
Thanks, Greetings,
Peter
