Struts 2.5.11 not serving iclass icons
I detected a strange issue. The problem is not present in 2.5.10.1 but
only in 2.5.11:
In jsp: <i class="fa fa-envelope-o"></i>
This will not show up as icon, but as kind of scrambled text. Using
struts2-tiles-plugin.
Hard to imagine to be struts related, but could this still be possibly
related to any of the recent changes?
Thanks for considering!

So this means something is wrong with Tomcat configuration, right? Or
you still see the issue?

Thanks for your patience!
Checking in browser => encoding
Tomcat serves the JSP as Unicode/UTF-8. The css is served as ISO.

Can you check how does it serve by a server?

Using
<i class="fa"></i> instead of <i class="fa fa-envelope-o"></i>
resolves the issue. But I still suspect a change in coding / treating
unicode in Struts.
The CSS starts with @charset "UTF-8";

Great! And don't worry, I'm so thankful that you have spent so much
time on testing the new release :) I prefer to postpone a new release
instead of introducing an inconsistency in minor versions ;-)

Thanks again for insisting so much on looking into this. I think I got
the (painful simple) root reason:
While further debuggin on the empty locale story, I did reset to
2.5.10.1 and then back again 2.5.11 and I also did clean the Tomcat
working directory...
...now setting up a test page like below, things work out! And helas,
even in the original page all three versions work out.
I am really sorry for this. Testing is hard and may lead to false
negatives: got 2 wrong and 2 right. I need to improve. ;-/

I was able confirm this somehow ... but I need your exact setup, what

There is no issue when I used a pure reference to FontAwesome (with

The CSS file seems to get through. The Layout is as should. The CSS file
is packed in a subdirectory of WebContent.
Nothing has been changed between 2.5.10.1 and 2.5.11. But do not mind
too much, if I have two working options:
The following works:
<i class="fa icon-envelope"></i>
<i class="fa"></i>

The following works:
<i class="fa icon-envelope"></i>
<i class="fa"></i>
The following does not work since 2.5.11:
<i class="fa fa-envelope-o"></i>
They all refer to the same icon.
They refer in CSS to:
.icon-envelope:before {
content: "\e086"; }
.fa-envelope-o:before {
content: ""; }
The later is the text being displayed since the upgrade.

Yes, the import statement is already there. It is a combined css file
(fonts and other CSS statements). Works perfect, also for 2.5.11. But
the webfonts seem to be treated differently, but only if used as <i
class="fa fa-envelope-o"></i>.
I worked around for this single case.

It isn't UTF tricks, it's a normal font definition and you must define
them in CSS first to use them:
<link rel="stylesheet" href="/css/font-awesome.min.css"
