Set Jackson's JsonReadFeature

[Dmitriy Bykov]

Hi.

In my application I receive JSON data from an external service, and sometimes it contains unescaped Unicode control characters, so when I try to call a JsonObject(data) on it, I get this exception: 

Caused by: com.fasterxml.jackson.core.JsonParseException: Illegal unquoted character ((CTRL-CHAR, code 27)): has to be escaped using backslash to be included in string value

Since it's an external system, I can do nothing to make it response with correct JSON, but I know that Jackson can deal with it just fine if the JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS is enabled on mapper creation.

Is there an easy way to enable this option for io.vertx.core.json.* classes?

Hi,

yes you can do that using the json modules used by vertx.

if you are on 3, this is a static method on the Json class, otherwise you need to look at the DatabindCodec class.

Thank you, I'll take a look.
