My code is

local textQues = display.newText( "test ทดสอบ", 20, 100,native.systemFont , 24 )

"test" is show but "ทดสอบ" not show

How i do ?

nuttty_99,
It works for me, see

I think this has got to do with the fact that the thai text is based on a particular font, now you said you are using windows, the font that you have that the simulator uses, might not have the Thai characters, for which you might be using a Thai font.

cheers,

@JayantV
you write test code

local textQues = display.newText( "test ทดสอบ", 20, 120,native.systemFont , 24 )
textQues:setTextColor(255,255,255)
