--------------------------------------
    Steps to Reproduce: 
# unzip WildFly and start via ./bin/standalone.sh
# in CLI perform following operations:
{code}
/subsystem=undertow/server=default-server/host=default-host/setting=access-log:add()
 /subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=allow-unescaped-characters-in-url,value=true)
/subsystem=undertow/server=default-server/https-listener=https:write-attribute(name=allow-unescaped-characters-in-url,value=true)
/subsystem=undertow/server=default-server/host=default-host/setting=access-log:add(use-server-log=true)

deploy helloworld.war
reload
{code}
# Now try to access WildFly server:
{code}
# First against HTTP listener:
curl "http://localhost:8080/helloworld/한글이름_test.html?param=한글이름_ahoy" -v >/dev/null
# Check result in access log

# Now try against HTTPS listener:
curl "https://localhost:8443/helloworld/한글이름_test.html?param=한글이름_ahoy" -v >/dev/null --insecure
# Check result in access log
{code}

> Since the time of {{EAP7.1.1.CP}} there is a possibility to allow unescaped characters in URL requests from clients to server. This was allowed first by setting {{org.wildfly.undertow.ALLOW_UNESCAPED_CHARACTERS_IN_URL=true}} system property introduced by UNDERTOW-1185. Now we have a new attribute for this in Wildfly in AJP, HTTP and HTTPS listeners {{allow-unescaped-characters-in-url}}.
> However this does not seem to work correctly. There have been some fixes for AJP listener already UNDERTOW-1386, UNDERTOW-1386 and UNDERTOW-1399 (the last one not included in WildFly {{14.0.0.Beta2}} yet). However HTTP/HTTPS listener seems to be broken too.
> When HTTP request with unescaped characters is performed against server:
> {code}
> curl "http://localhost:8080/helloworld/한글이름_test.html?param=한글이름_ahoy" -v >/dev/null
> {code}
> we get 200 OK HTTP response, although the result in access log looks like:
> {code:title=HTTP actual result}
> 127.0.0.1 - - [27/Aug/2018:09:17:39 +0200] "GET /helloworld/한글이ë¦
>                                                                        _test.html?param=한글이ë¦
>                                                                                                    _ahoy HTTP/1.1" 200 950
> {code}
> but we expect following:
> {code:title=HTTP expected result}
> 127.0.0.1 - - [27/Aug/2018:08:40:47 +0200] "GET /helloworld/한글이름_test.html?param=한글이름_ahoy HTTP/1.1" 200 950
> {code}
> Slightly different problem seems to be also for HTTPS listener. When we perform HTTPS request against WildFly:
> {code}
> curl "https://localhost:8443/helloworld/한글이름_test.html?param=한글이름_ahoy" -v >/dev/null --insecure
> {code}
> we receive 404 Not Found HTTP response and following record in access.log:
> {code:HTTPS actual result}
> 127.0.0.1 - - [27/Aug/2018:09:18:37 +0200] "GET /helloworld/￭ﾕﾜ￪ﾸﾀ￬ﾝﾴ￫ﾦﾄ_test.html?param=￭ﾕﾜ￪ﾸﾀ￬ﾝﾴ￫ﾦﾄ_ahoy HTTP/2.0" 404 68
> {code}
> however expected result should be similar to what we expect for HTTP, I guess.
