work now including saving/opening games. Network play probably
doesn't as writing/reading a dict from stream has to change. It's
doubtful patches from this branch will be merged. Rather, I'll take
the concepts and crib some code when re-implementing. Concepts:
XP_UCHAR becomes UTF-8 on both platforms, and on wince we translate to
wchar_t just as now but from the utf-8 codepage. That keeps the work
and risk to a minimum.
