Created attachment 184813 [details] Large space characters The attachment has three pages, each of them listing the Unicode characters from 'Separator, Space' category [Zs]. The first page uses normal paragraphs, the second and the third have tables with them. The space characters are formatted with text size 48, while labels have size 12. In Word, some paragraphs on the first and the second pages have resulting height corresponding to text size 12, ignoring the height of space characters on them. These lines are marked red. On the third page, all table rows have automatic heights corresponding to text size 48. This is related to the IgnoreTabsAndBlanksForLineCalculation compat flag.
