------- Additional comments from [EMAIL PROTECTED] Sun Feb 6 23:26:30 -0800 2005 ------- A combining character sequence such as gor gai+mai ek+sara ii (0e01+0e48 +0e35) is not displayed properly on Windows. It should be displayed as gor gai with the mai ek and then dotted circle with sara ii. It *is* displayed in this way in Linux. On Windows, with the old Windows Thai fonts, such as Angsana and Browalia, an ugly black box is show, and it is not clear that there is a sara ii there. Much more seriously, with more recent fonts such as Tahoma, the sara ii does not show up at all. The combining character sequences that are not displayed properly are sequences that Windows cannot display in a single cell. Such sequences never occur in correct Thai. Conventionally, most applications on Windows prevent the input of such invalid sequences. However, OOo does not always do this and it is anyway possible for such sequences to occur in imported data. It is important that such sequences be highly visible to the user so that the user can correct them. Test case: 1) Load the attached document (with invalid combining character sequences) on Linux. The display use dotted circles to ensure that all combining characters in invalid combining character sequences are clearly displayed. See the first screenshot attached. 2) Load the same document on Windows. You'll not see any dotted-circle. See the second screenshot. So you'll not know that this document has errors in it. 3) Reformat the document to use the font Angsana (or Browallia or other Windows Thai fonts). You'll see black boxes where there are invalid combining character sequences. See the third screenshot. This let you know that there're errors but you can't tell what the error is. Using Tahoma or Microsoft Sans Serif or Lucida Sans Unicode (which have the glyph for dotted circle) instead, and there are no black boxes but there are no dotted circle either. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
