Some things I see you have wrong: first, you are including win32ax.inc instead of win32wx.inc and second, you are not currently including what encoding you are using (perhaps the one you have commented now is the one you must use but that depends of your editor).

Perhaps there are other errors but the ones I've told must be fixed before anything else.

First thanks ,then i do like you said,but the problem is still on, also i replace the APIs with 'W' edition,but i cant solve the problem

OS:windows xp professional sp2 simplified chinese edition
compiler:Fasm V 1.67.29

1. use win32wx.inc
2. enable include 'encoding\utf8.inc'
3. use other editor which has utf-8 like scite and save the file using utf-8 encoding
4. run it

you should be able to view the text.

This is a related thread with some solutions.

Another board member found a very simple solution for using NotePad with BOM - just make EQU at first line: ...and it will include the BOM bytes together with the equate name -- helping FASM process the file.

In fact, the simplest trick would be to just put the colon on the very beginning of file - so that the BOM would become the label.
This works great, when put at the start of source saved into BOM-marked file:
