Subject [jira] [Commented] (COUCHDB-1624) CouchDB shouldn't accept or serve JSON with control-characters

Michiel Meeuwissen commented on COUCHDB-1624:
---------------------------------------------

Svenson uses the java-definition of a 'iso control character': 

 public static boolean isISOControl(int codePoint) {
        return (codePoint >= 0x0000 && codePoint <= 0x001F) || 
            (codePoint >= 0x007F && codePoint <= 0x009F);
    }

> According to http://www.json.org/ control-characters are not valid characters in JSON.
Due to a character encoding bug one of our applications was sending JSON with control-characters
to CouchDB. CouchDB happily accepts this (invalid) JSON and also serves it, but then we started
getting problems in a client that uses the Svenson JSON library which (correctly) complains
about invalid characters in the JSON served by CouchDB.
