Apache OpenOffice (AOO) Bugzilla – Issue 126666
Symbol for the Product operation (Pi) is malformed
Last modified: 2017-05-20 09:46:38 UTC
The issue was originally reported on the dev list by Howard Morris, using Windows 10. Confirmed by Patricia Shanahan on the dev mailing list: "I am seeing similar problems with the product formula symbol. Exported as PDF, it looks fine. Viewed in Writer, the capital Pi lacks serifs, making it look very strange. When I click on it in the formula editor, it is at the bottom left of a dotted box, and the limits are aligned relative to the box. Not WYSIWYG. The fonts are: Variables: Times New roman, Italic Functions, Numbers, Text, and Serif: Times New Roman Sans: Arial Fixed: Courier New I have uploaded the files to http://www.patriciashanahan.com/OpenOffice. product.bmp is a screen shot of the formula editor. product.odt is the actual file. product.pdf is the PDF export." Patricia was using Windows 8.1 I cannot reproduce it using Windows 7 or Redhat Linux. Of course, the operating system may not be the important variable. The bmp mentioned above is attached.
started a thread I on the en forum: https://forum.openoffice.org/en/forum/viewtopic.php?f=12&t=80398
Those are not malformed. Rather at Windows 8.1, and also Windows 10, the OS is using the "Segoe Symbol UI" font pulling from the Mathematical Operators page U+2200. Through Windows 7 and with prior AOO 3 and 4 builds, the Math module worked from OpenSymbol font if installed. So, this is technically not a bug as it is imposed by the OS. Project now needs to figure out how to resume use of the visually more appealing OpenSymbol font page.
And, this has been around for some time. Closing this as a dupe of bug 124203. *** This issue has been marked as a duplicate of issue 124203 ***
I applied the workaround from the duplicate bug, and it did improve the appearance of the capital Pi.
