Issue with Richfaces file-upload for files having multi byte character filename

[user4]

While uploading files using Richfaces having multi byte character filename, file upload listener is not getting called if filename has some special characters. UTF-8 encoding is set in xhtml page as well as filter file

XHTML file snippet:

<h:form id="form" enctype="multipart/form-data;charset=UTF-8;" acceptcharset="UTF-8" >
...
<rich:fileUpload id="upload" fileUploadListener="#{fileUploadBean.uploadListener}" immediateUpload="true" addControlLabel="Add" acceptedTypes="csv" >
     <a4j:ajax event="uploadcomplete" execute="@none" />
</rich:fileUpload>
...
</h:form>

I am using Richfaces 4.5.9. Is there any bug in richfaces file-upload or am I missing any configuration?

Could you use syntax highlighting instead of a quote? (It's the last button on the second row.) This is pretty much unreadable.

Unfortunately the encoding of the file is handled by the server, the encoding of the html page or the form doesn't matter. Check if your server has any setting that could change it. You can try debugging this method, to see what encoding is being detected.

We are using wildfly 9 as application server.

Default encoding set and detected is UTF-8

Hi Michael,

Any inputs on this?

Can't provide much input over the holidays I'm afraid.

Does the filename come with bad encoding then?
