Subject [jira] [Commented] (HTTPCLIENT-1708) Issues With Extended ASCII ( Latin Chars ) Escaping with HttpClient 4.5.1
Date Mon, 28 Dec 2015 19:23:49 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15073049#comment-15073049

Oleg Kalnichevski commented on HTTPCLIENT-1708:

What is it _specifically_ that HttpClient does incorrectly? If you think URI#toASCIIString
garbles input you should raise the issue with Oracle.

> Hey Guys
> Trying to send an httpclient HttpHead request for the following url  - 'http://some.domain.com/amnetcanadaplatform/HomeDépot_Électros_WEB22s_video.mp4'
> I Notice it gets escaped as 'http://some.domain.com/amnetcanadaplatform/HomeD%C3%A9pot_%C3%89lectros_WEB22s_video.mp4'
> While other programs/utilities/frameworks expect it to be 'http://some.domain.com/amnetcanadaplatform/HomeDe%CC%81pot_E%CC%81lectros_WEB22s_video.mp4'
> I've done some digging up the source code and tracked the issue down  to  "toASCIIString()"
of the Java URI ( WHICH OF COURSE IS NOT YOUR RESPONSIBILITY )object being called in order
to retrieve the request line
> Class : org.apache.http.client.methods.HttpRequestWrapper
> Method : getRequestLine() 
> Line : 113
> Internally the line 'String ns = Normalizer.normalize(s, Normalizer.Form.NFC);' manipulates
the chars so their unicode value changes , which causes the 'inappropriate' values to be displayed
for the escaped URI 
> Class : java.net.URI
> Method : encode(String s)
> Line : 2723
> Now I know this would extra hard to even get to a point where I find out if this is a
java language issue , but I don't believe unicode manipulation  of bytes is a desired behavior
 for url encoding. Is there any known specific why you used the "toASCIIString()" method instead
of the plain "toString()" method
> Do you think there's a chance this issue can be resolved on your end ?
