    local input = editbox.new(TTFont.new("simhei.ttf",40,""),'')

    editbox = Core.class(TextField)

    function editbox:init(ttf,string)
    self:addEventListener(Event.KEY_CHAR,self.key_char,self)
    end

    function editbox:key_char(e)--over five char(utf8 chinese) can't get it,and how to achieve it (over five char)
    local str = self:getText()..e.text
    self:setText(str)
    stage:addChild(self)
    end

      I can have over 5 characters this way but I don't have a chinese keyboard to check when typing other letters:
      editbox = Core.class(TextField)
 
function editbox:init(xttf, xstring)
	self:addEventListener(Event.KEY_CHAR, self.key_char, self)
end
 
function editbox:key_char(e)--over five char(utf8 chinese) can't get it,and how to achieve it (over five char)
	local str = self:getText()..e.text
	self:setText(str)
	stage:addChild(self)
end
 
----
 
application:setBackgroundColor(0x555555)
local text = "你好世界！, 你好世界！"
local input = editbox.new(TTFont.new("fonts/simhei.ttf",40,""), text)
input:setPosition(64, 64)
stage:addChild(input)

      emm...
      if use english keyboard ,every time when you input, "e.text" just 1 byte.

      and i seen "application:setTextInput()" ,but it can't work in win32.

      luyimoon I think you may need the harfbuzz plugin.


      It is not documented in the wiki but I believe you just need to add it to your project and the textfields will use it.
      https://forum.gideros.rocks/discussion/7954/textfield-rtl-text-coloring

      and when harfbuzz was added to gideros as a plugin:
      https://forum.gideros.rocks/discussion/7620/arabic


      For non latin language each letter will be 1 byte and for eastern languages 2 or more bytes.

      Key char event was supposed to report only one character at a time, I am surprised you can even get more than one already. On which os/platform is this happening ?

      Ok, I understand, your input engine buffers characters and supply a whole sentence to the system, instead of individual characters. Gideros buffer is limited to 16 bytes (here: https://github.com/gideros/gideros/blob/master/libgid/include/ginput.h#L144), because we assumed it was enough to old two or three UTF-8 characters resulting from a composition sequence.
      As a quick way to make it work for your case, I can enlarge the buffer, but what would be a reasonable size ? 1024 would allow more than 300 3-byte characters, is that enough ?

      i think 1024 is enough.
      :D
