Subject: [PATCH] UTF-8 encoding to rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without this addition the rules cannot accept words that contain non ASCII characters (for example the word siccità) and the API returns the error "{"errors":[{"parameters":{},"message":"Invalid JSON"}],"title":"Invalid Request","detail":"One or more parameters to your request was invalid.","type":"https://api.twitter.com/2/problems/invalid-request"}"
