Malformed Product (Pi) symbol in 4.1.2

[FJCC]

An issue with the product symbol, upper case pi, has been reported on the dev list and confirmed by one other person. A formula such as

Code: Select all   Expand viewCollapse view

prod from {x=1} to 10 x+5

produces an odd looking Pi without serifs in Writer, though the PDF export looks fine. The two users used Windows 8.1 and 10. I cannot reproduce the defect on Windows 7 or Redhat Linux. I opened
a bugzilla issue 126666.

Can anyone else reproduce the problem? Any suggestions about what is going on? Files related to the problem are at http://www.patriciashanahan.com/OpenOffice

Seems ok for me (4.1.2rc3 on Linux)

I have installed aoo 4.1.2 on a Windows 7 laptop, and it does not reproduce the problem. I see a beautiful capital Pi, occupying the whole of its frame, and everything properly aligned. I am pushing ahead with trying to build. If I can do that, I can put the Windows 7 laptop next to the Windows 8 computer that reproduces the problem, and do comparative debug.

In AOO 4.1.2 on Windows 10, I opened Formula (OpenOffice Math) and entered the code directly into it. I see the same problem with the capital Pi and centering of the above and below items. (The Pi looks left aligned rather than centered beneath the over/under rows.)

This isolates more to be looked at in the saved document.

An amusing aspect of this for ODF-wonks is the use of the settings.xml file for something that is not quite what the intended purpose of that is. Since settings.xml is implementation specific (and documented who-knows-where for OpenOffice.org).

Here are some more results:

For the *.odf (Formula) file on Windows 10, both Apache OpenOffice 4.1.2 and LibreOffice 5.0 show the same defect.

For the *.odt (Text) file on Windows 10, both Apache OpenOffice 4.1.2 and LibreOffice 5.0 show the same defect. Microsoft Office Word shows the product notation entirely as expected; there is extra space between the product symbol and the "x + 5". I can't tell if that is showing where something is expected in the Equation Design or it is an actual space. It may be that the {x + 5} is needed in the OpenOffice Math entry. Something to check.

I see no problem with the quoted code using AOO412m3(Build:9782) - Rev. 1709696 on WinXP SP3 (where I am coding at the moment).
I am using the STIX font.
What font is used where a problem is seen?

Perhaps read [Solved] Symbols font on Windows 8.1. OOo 3.2 on Mac OS X 10.9.5 produces a nice pi symbol with serifs.

If this solved your problem please go to your first post use the Edit button and add [Solved] to the start of the title. You can select the green checkmark icon at the same time.

The bugzilla issue I opened has been closed as a duplicate of 124203. It is indeed the issue linked by MrProgrammer.

[pats@acm.org]

I think it is a duplicate in the sense that both are about failure to use a suitable font for the math symbols. I tried the workaround, forcing Cambria Math for OpenSymbol. It did put serifs on the capital Pi, but the alignment is still not quite right.

Another possible workaround:
Using my "old" (2013-01-29) opens___.ttf I can resort to (e.g.):

Code: Select all   Expand viewCollapse view

oper %PI  from {x=1} to 10 (x+5)

In the attached example (fake extension due to forum software's stubbornness) I get the "ugly hook" using the 'prod' command and a well formed uppercase pi with serifs using the 'oper' command with %PI.
(The updated OpenSymbol fonts offered in https://forum.openoffice.org/en/forum/v ... 12&t=67772 did not work satisfyingly for me. I got the PI only on the screen but not when printing - and did not understand why.)
