no verification of incorrect UTF-8 codes in the path URI
the implementation of the HTTP request parser does not process the correctness of UTF-8 codes, which makes it possible to transmit sequences that take up 2 bytes, but produce the character code ".". This causes the request to be ignored by modules set to the URI path "/.". For this reason, the server may be sending data that is not allowed to be sent.
