This is a problem for > how does LO handle character orientation for such characters. I guess the actual issue is that we don't know how we should initialize font properly. In Windows we prepend @ to the font name to indicate it is for vertical writing and set font Escapement and font Orientation to the text orientation ( i.e. 270 for vertical writing ). Somehow that works for most characters in SMP but not for BMP, but that might be a coincidence. It might also be font dependent so that the characters work correctly even they are in SMP. Maybe we can create some test with EXT-B characters and render them in HanaMinB ( assume the font is implemented correctly for EXTB characters ) to verify our assumption. If we can differ the characters, then we can set the orientation correctly for those characters.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
