11:29 AM Ruby Bug #13217 (Rejected): JSON.parse() chokes on the UTF-8 character EM SPACE (U+2003, e2 80 83)

### Steps to reproduce
No error here:
```
require 'json'
json = %Q{
["a", "b"]
}
obj = JSON.parse(json)
```
But there is a UTF-8 space character called `EM SPACE` (U+2003, e2 80 83), which looks like a regular ascii... 7stud (7 stud)
