how to handle special characters ( " ) in input file logstash - elasticsearch

Question

i'm having a problem with my data when push to ELK using logstash.
here is my input file
input {
file {
path => ["C:/Users/HoangHiep/Desktop/test17.txt"]
type => "_doc"
start_position => beginning
}
}
filter {
dissect {
mapping => {
"message" => "%{word}"
}
}
}
output {
elasticsearch{
hosts => ["localhost:9200"]
index => "test01"
}
stdout { codec => rubydebug}
}
My data is
"day la text"
this is the output
{
"host" => "DESKTOP-T41GENH",
"path" => "C:/Users/HoangHiep/Desktop/test17.txt",
"#timestamp" => 2020-01-15T10:04:52.746Z,
"#version" => "1",
"type" => "_doc",
"message" => "\"day la text\"\r",
"word" => "\"day la text\"\r"
}
Is there any way to handle the character ( " ).
i want the "word" just be like "day la text \r" don't have character \"
Thanks all.

I can explain more about this if this change works for you. The reason I say is I have newest mac so I don't see the trailing \r in my message.
the input just like you have it "day la text"
filter {
mutate {
gsub => [
"message","(\")", ""
]
}
}
response is
{
"#timestamp" => 2020-01-15T15:01:58.828Z,
"#version" => "1",
"headers" => {
"http_version" => "HTTP/1.1",
"request_method" => "POST",
"http_accept" => "*/*",
"accept_encoding" => "gzip, deflate",
"postman_token" => "5ae8b2a0-2e94-433c-9ecc-e415731365b6",
"cache_control" => "no-cache",
"content_type" => "text/plain",
"connection" => "keep-alive",
"http_user_agent" => "PostmanRuntime/7.21.0",
"http_host" => "localhost:8080",
"content_length" => "13",
"request_path" => "/"
},
"host" => "0:0:0:0:0:0:0:1",
"message" => "day la text" <===== see the extra inbuilt `\"` gone.
}
