I confirmed that bug, and found that the problem is not specific to Windows port. As there were comments paying attention to anti-aliased drawing in xdisp.c, I didn't change code for handling overlapping when I committed font-backend codes, but I just found that there is a fundamental bug. I'm now investigating how to fix it. --- Kenichi Handa handa@m17n.org
