lpli,
Could you please state your Eclipse, MyEclipse, Java versions and OS?
Are you using the new JSP designger or the old JSP editor? (New JSP designer was released with ME 4.0M3)
Are the chines characters being displayed correctly on the source page, but only not displaying on the Preview page?
If you make some changes, save and reopen your file, do the chinese characters remain as expected?
Best,
Brian.
