J=C3=BCrgen Weber commented on JSPWIKI-396:
--------------------------------------

OK, this is quite subtle. Weblogic relies on that the wrapping ServletOutpu=
tStream is an OutputStream, i.e. backed by a byte[]. For u umlaut (Unicode =
C3 BC) Weblogic strangely sends  =20
-61  FFFFFFFFFFFFFFC3=20
-68  FFFFFFFFFFFFFFBC
In byte[] this ends as C3 BC, new String(C3 BC) correctly gives u umlaut.
But currently WikiJSPFilter uses a CharArrayWriter, which uses char[] and s=
tores u umlaut as FFC3, FFBC.char[].toString() yields the strange character=
s one sees. For Tomcat this seems to work by chance, probably the ServletFi=
lter returns C3 BC as two chars which the browser combines into the unicode=
 char.

U+00FC=09=C3=BC=09c3 bc=09u umlaut

Actually, I don't see the need for WikiJSPFilter, it just caches, and cachi=
ng should be left to the appserver.=20

Anyway, the appended patch fixes the Weblogic problem and does not break To=
mcat.

> The Germain Main.txt starts with Herzlichen Gl=C3=BCckwunsch.
> If the page is served by Weblogic Server, the umlaut is rendered with FFC=
3 and FFBC in Boxes, both with Firefox and IE. Served by Geronimo, it's fin=
e.
> Herzlichen Gl=EF=BF=83=EF=BE=BCckwunsch
> Firefox page info says, page encoding is UTF-8.
