Some questions about getText() and setText() in lua

[kitejohn]

Sample_Demo8:
code as follows:
local text = winMgr:getWindow("Demo8/Window1/Controls/Editbox"):getText()
winMgr:getWindow("Demo8/Window1/Controls/Editbox"):setText(text)

if the string text contains Chinese characters,then i call setText(text),now
you can't see the text of editbox,it has been confused,you just can view another symbol.

I use font simhei-12.font, you can set Chinese characters in c++ code,
for example setText((utf8*)"中"),the editbox can show right, but call
getText() then call setText() in lua,it fails.

tolua++ simply maps lua 'string' as CEGUI::String. and tolua++ deals strings as 'const char*'

when u call 'Window::getText',, CEGUI::String automatically decode utf32 string to utf8 and returns utf8 pointer, then 'Window::setText' gets it as 'const char*' so.. CEGUI::String do the encode to utf8 again,,

i got the same prob. in korean lua scripting,, and i got a temporal solution that casting NOT 'const char*' but 'utf8' (in lua_CEGUI.cpp)
so it works for me..

sorry for short english, good luck
