hi Nikhil,

they are different PullParser2_1_8_SMALL.jar is XPP2,
for XPP3 you would have xpp3_1_1_2_min.jar, ex:
http://www.extreme.indiana.edu/xgws/xsoap/xpp/download/xpp3/

for simplicity current XPP3/MXP1 (or XPP2) does not do
detection  of input encoding :-(

it is not very difficult to implement but requires very careful coding
to switch during processing "raw" InputStream into appropriate encoding.

in general you can check that if XmlPull parser support encoding detection
using this feature: http://xmlpull.org/v1/doc/features.html#detect-encoding

you could try in meantime to use XNI2XmlPull that is based on Xerces2
that will do encoding detection or as with any other open source projects
if you get this fixed in XPP3 then  patch will be gratefully accepted
(and  you will be appreciated by mentioning it in docs and by other XPP3 users :-))

thanks,

alek
