Errata type: Others | Page number: 47

On page 47, the mentioned definition for "add_charset" is wrong. The correct one is as follows:

add_charset: This specifies a list of response content types (for example, 'application/json'). When preparing a response, if Sinatra finds that the type of response is one of the types in the list, it adds a character set indicator to the Content-Type header. Note, that normally, you should replace the existing list, but it is better to add to it, for example, settings.add_charset << "some/type".
