As soon as i heard U++ from one of my friends, i tried it but found some language support problem about Chinese.
The errors come from a sort of *.t files, with some lines like:
zhCN("所有页\n当前页\n始于页")
which seem to be resource strings.The error messages like:
C:\upp\uppsrc\CtrlLib/CtrlLib.t(2430) : error C2001: newline in constant
The demo applications i built would could not be compiled and executed unless i commented these lines like above.
This is known stupid problem of MSC compiler.
The only known workaround is to switch your windows to english locales.
