I have below config in brief, where i am trying to rename the field name to have a special character (degree symbol) but using it throws an error.
"'The following config files contains non-ascii characters but are not UTF-8 encoded".
config file:
input{
// from sql server
}
filter{
mutate{
rename=>{"temperature" => "Temperature(°C)}
}
output{
elasticsearch{
------------------
------------------
}
}
Can someone help me!
