Tony,

if your choice of package is based solely on whether it supports
unicode or not, I would probably recommend Microsoft's Excel or
OpenOffice's Calc. However since you are in this forum, you probably
intend to do some statistical processing of that information. In that
case what is that analysis? In many cases you actually don't need to
see the text, but just rely on the package to handle it. If you don't
want to specify, consider SPSS or SAS which (according to the
manufacturers) both support unicode. I have also asked if new Stata 13
supports unicode and hope for the best. If you want to harvest
information about the user profiles, you will need to check with the
site owner whether this would be permitted, and if you have valid
scientific needs to do it, perhaps, the owner might simply pass that
information to you in an organized way. From what it appears on this
page you can pull some information like ID, age, gender, phone, and
province, and the rest (name, address) is hardly of any value for
statistical processing.

Best, Sergiy
