----=_hbfuk6lufh19t8k06j49n5ic2no9i43qi3.MFSBCHJLHS Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I think I have found a bug with UTF-8 output in a console in a UTF-8 locale ("C.UTF-8"). If an UTF-8 character straddles a write() boundary, then the output gets garbled. An example program is attached. ----=_hbfuk6lufh19t8k06j49n5ic2no9i43qi3.MFSBCHJLHS Content-Type: application/octet-stream; name=buftest.c Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename=buftest.c I2luY2x1ZGUgPHN0ZGlvLmg+CgppbnQKbWFpbihpbnQgYXJnYywgY2hhciAq YXJndltdKQp7CglpbnQgaSwgYnVmOwoJCglpZiAoYXJnYyA+IDEpIHsKCQli dWYgPSBhdG9pKGFyZ3ZbMV0pOwoJCWlmIChidWYgPD0gMCkgcmV0dXJuIDA7 Cgl9IGVsc2UgewoJCWJ1ZiA9IDU7Cgl9CgkKCXByaW50ZigiRmlyc3QgYSBz ZXF1ZW5jZSBvZiBjaGFyYWN0ZXJzLCBhLXJpbmcsIGEtZGlhcmFlc2lzLCBv LWRpYXJhZXNpcywgcmVwZWF0ZWQ6XG5cbiIpOwoJCglmb3IgKGk9MDsgaTwy NTsgaSsrKQoJCXByaW50ZigiXHhjM1x4YTVceGMzXHhhNFx4YzNceGI2Iik7 CgoJcHJpbnRmKCJcblxuIik7CgkKCXByaW50ZigiTm93IHRoZSBzYW1lIHRo aW5nIHdpdGggYSBidWZmZXIgb2YgJWQ6XG5cbiIsIGJ1Zik7CgkKCXNldHZi dWYoc3Rkb3V0LCBOVUxMLCBfSU9GQkYsIGJ1Zik7CgkKCWZvciAoaT0wOyBp PDI1OyBpKyspCgkJcHJpbnRmKCJceGMzXHhhNVx4YzNceGE0XHhjM1x4YjYi KTsKCglwcmludGYoIlxuIik7CQoKCXJldHVybiAwOwp9Cg== ----=_hbfuk6lufh19t8k06j49n5ic2no9i43qi3.MFSBCHJLHS Content-Type: text/plain; charset=us-ascii -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ----=_hbfuk6lufh19t8k06j49n5ic2no9i43qi3.MFSBCHJLHS--
