A emoji parameter bug On Linux
Platform: Linux(not happen on Mac)
What happen: the server shutdown
How to happen: remove permeter escapeVS, request body is '👨👩👧👦'
Strange: set parameter escapeVS or request not contains '👨👩👧👦', this wouldn't happen.
My question: Is the postParams wrong when the request body contains some speical emoji?
this is my request:
curl --location --request POST 'http://localhost:8181/emoji/parse?a=b' \
--header 'Content-Type: text/plain' \
--data-raw '👨👩👧👦'
this is my code:
func emojiParse(request: HTTPRequest, response: HTTPResponse) {
do {
let escapeVS = request.param(name: "escapeVS", defaultValue: "false")?.elementsEqual("true") ?? false
if let raw = request.postBodyString {
response.setHeader(.contentType, value: MimeType.forExtension("json"))
let result = raw.translateUEmojiCode(escapeVS)
try response.setBody(json: result)
}
} catch {
response.status = .internalServerError
response.setBody(string: "Error handling request: \(error)")
}
response.completed()
}
this is my debug on Mac:
this is the error log:

--------UPDATE----------
this request also trigger the bug.
curl --location --request POST 'localhost:8181/emoji/parse?escapeVS=false&👨👩👧👦=b' \
--header 'Content-Type: text/plain' \
--data-raw '123xds'
--------UPDATE----------
Looks like a swift unicode bug on Linux?
