--- Comment #20 from Jonathan Clark <[email protected]> --- OpenType fonts contain an OS/2 table which specifies metrics and other common parameters. One field in the OS/2 table is uCodePageRange*, a bitset which fonts can use to indicate whether the font covers a particular code page. When bit 17 is set (indicating CP932 coverage), Microsoft Word may automatically extend the line height using an unknown algorithm. Based on manual testing, I believe this extra line height is roughly equivalent to 136% proportional spacing in Writer. This behavior affects any font that has the CP932 bit set, regardless of metrics, whether it is used for Asian text, whether the text contains CJK characters, whether the font actually contains CJK characters, or whether the document grid is in use. In my experiments, simply setting this bit on a font and loading an existing document that uses it is enough to reproduce this behavior. -- You are receiving this mail because: You are the assignee for the bug.
