This problem persists after I installed 4.2.3.1 release

Did you install any specific extensions or fonts?
Could you rename your LO directory profile (see https://wiki.documentfoundation.org/UserProfile#Windows) and give it a new try?

I tried renaming the user profile (and it was recreated) but it didn't change anything. I installed some fonts but that was ages ago and I didn't have any problem with LO at the time. (and now that I think about it... probably not even on my present computer)
I have the Liberation family, linux libertine and Linux biolinum, is that normal ?

And I didn't install any extension on this computer.

Thank you for your feedback. Since I don't have more questions, I put it back to UNCONFIRMED

It looks like Wingdings is used to render symbols in Unicode-plane latin-1. Enter " + ± * ÷ " in Writer and format with Wingdings. Result are the symbols in the attachment.

It seems that editor is looking for a some font, which is missing. So the last one (Windings) is used instead. And the final result is UNACCEPTABLE. 

Please see similar bug 77923.

same problem here! libreoffice 4.2.4.2, windows 8.1
we really need a fix for this problem!

Hi

Exact the same here: Win7 x64 LO 4.2.4.2. This ugly regression makes LO unusable in some use cases! Please fix!

Cheers

The problems disappeared for me with the installation of the 4.2.4.2 though apparently that's not the case for everyone.

Thank you Chaddaï for your feedback.

ahonx/ralph: even after having renamed your LO directory profile (see https://wiki.documentfoundation.org/UserProfile)?

e_psi/js44: did you give a try with LO 4.2.4 (and a brand new LO profile)?

Yes. This was my first assumption, but it does not help.

I usually change the default font, so I had hope that it will fix my problem. I have checked it on the Linux, and there such problem was not present. I think that my Windows 7 x64 installation have some missing fonts, so it would be nice to know which font is selected for making formulas with those operators.

The font is called "OpenSymbol" (the file name is opens___.ttf). This font should come bundled with LO. So the first step is to check whether you have this font installed.

Sometimes wrong registry entries can also prevent a font loading, so you could try to run some registry cleaner (like CCleaner). Uncheck all checks except the fonts one, repair any found problems, and reboot.

I have downloaded OpenSymbol font from:

http://www.fontpalace.com/font-download/OpenSymbol/

Then I have installed them, and it helps. 

Thanks Maxim for the info

For all other people, please check if you have file OpenSymbol.ttf in \Windows\Fonts directory

Now I have made little more improvement. I took opens___.ttf from OpenOffice installer *.msi file. My previous comment 17 does not provide all symbols.


To obtain opens___.ttf from msi (adapted from http://thebackroomtech.com/2007/08/23/howto-extract-files-from-a-msi-file-using-the-windows-command-line/)

Run from command line:

msiexec /a LibreOffice_4.2.4_Win_x86.msi /qb TARGETDIR=%USERPROFILE%\testE

After extraction go to %USERPROFILE%\testE\Fonts directory, for example this can be done via next command

explorer %USERPROFILE%\testE\Fonts

Find opens___.ttf file, double click on it and use "Install" button in the font browser.

I also discovered the bug in my LibreOffice 4.2.6.2 installation on Windows 7 (64 bit). However another Windows 7 (64 bit) installation with 4.2.6.2 also doesn't show the effect. The difference was this: The first was a new install of some 4.2 release (then updating to the current release) while the other was an update from an earlier version (< 4.2, I don't know the initially installed version, maybe 3.2 or so). Is this issue really resolved, or are there just work-arounds?

To move this into a useful direction: please test and see if this bug persists with LO 4.3.1: https://www.libreoffice.org/download/pre-releases/

Please also try resetting your user profile and let us know if that helps: https://wiki.documentfoundation.org/UserProfile

Should the issue be persisting, please
a) set this bug to REOPEN
b) attach a testfile illustrating this issue

I don't quite understand: The original report was against 4.2.1, and comment 16 says the font should come with LibreOffice (installation/update). I confirmed that even in 4.2.6 the issue (font not installed? why?) is still present (as comment 13 also says), so if LibreOffice has the font packed, it doesn't properly install it. Reason?

No you have no plans to fix this major bug for 4.2, and refer to _trying_ 4.3.
Do you really want users to leave LibreOffice alone? Every new release seems to break existing features, and you always say "try the next major version". Don't you understand that people don't want new features, but something that works reliable?

Andras:  problem of OpenSymbol which wouldn't be on LO Windows install package LO package. One for you?

For me the bug vanished after installing LibreOffice_4.2.7_Win_x86.msi.

Same problem (missing OpenSymbol -> wrong symbols in formulas and panel) after upgrading 4.2.5.2 to 4.3.3.2 under Win7x64.

After extracting msi and checking contents of Fonts subfilder, I see that some fonts are present in my Windows\Fonts, some other are not. I don't know which should have been installed, and cannot check on test system at the moment, so I simply post the list.

I'm pretty sure no other installed software references these fonts.

Hi,
I have had the same problem in LibreOffice 4.2.7.2 on Windows 7 and right now I have fixed the problem.

From duplicate bug report: https://bugs.freedesktop.org/show_bug.cgi?id=76239#c17 I got an info how to fix the problem.

Details:
1. Open cmd window and check for font: dir %windir%\Fonts\opens__.ttf
   If "File Not Found" error is returned then it is a missing font.
2. Click on link: http://cgit.freedesktop.org/libreoffice/core/plain/extras/source/truetype/symbol/opens___.ttf and download file.
3. Open Windows Explorer and double click on opens___.ttf file and click on Install button at the top of window.
4. Recheck the command from step 1.
   Note: I got to be honest, I don't know why downloaded ttf file has 3 underscores in file name so opens___.ttf, but installed font in C:\Windows\Fonts has only 2 underscores like opens__.ttf.
   It is strange to me why underscores are used in the first place, to make confusion...

PROBLEM SOLVED in my case.
Hope this helps.

It's indeed interesting to keep fdo#84715 in See Also since the problem seems similar, perhaps a dup?

*** Bug 86406 has been marked as a duplicate of this bug. ***

It would be good to have installer logs to see what really happened.

msiexec /i LibreOffice-x.x.x.msi /L*vx log.txt

For me, the bug did not occur in case of 4.2.4 -> 4.2.6 and 4.2.6 -> 4.3.2 upgrades on Windows 7. 

The root of all evil may be this commit:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=0404f37297c4b283972d71c8f53765d9169bdafa
fdo#68194 Font files are left after uninstallation
#i119948# Instruct windows installer to use refcounting on fonts.

The intention was to please Windows 8 App verifier, i.e. an application should not left files after itself after uninstallation. It has side effects. For example, LibreOffice will remove non-refcounted (manually installed) fonts. Maybe this bug is also a side effect of this (but it's hard to understand why).

this dupe indicates that the issue still affects the 4.3.x branch
I move this bug to the mab4.3 list since 4.2.x is END OF LIFE

*** Bug 86918 has been marked as a duplicate of this bug. ***

I updated my libreoffice from 4.2.6.2 to 4.2.7.2 and this bug appeared exactly as reported as follows:
https://bugs.freedesktop.org/show_bug.cgi?id=80643

I need to install Open Symbol font manually to solve it.

don't change version field
it should indicate first version the bug appeared, not latest.

On my side it's working again with version 4.3.4.1

please guys, try all to upgrade from 4.2.x to 4.3.x and tell if the issue is fixed in the new branch. if yes we could mark this as RESOLVED WORKSFORME

See comment 30

thanks Mike.
that was a 4.2.5 to 4.3.3 upgrade.
I wonder if the bug is still present in a 4.2.7 to 4.3.4 upgrade or in a 4.3.x to 4.3.4 upgrade

(In reply to fox_yadvfw from comment #41)
> On my side it's working again with version 4.3.4.1

Fox, which was the old version from which you did the upgrade?

IMO, you cannot close it as WFM, just because all subscribers here say that next upgrade didn't show the problem.

It seems that the problem is somehow state-dependent. E.g., I have met it only 4.2.7->4.3.4, while every previous upgrade went smoothly (and upgrading to the same version on several other PCs went OK, too).

And if most people here have installed fonts manually, this could just hide the bug as well.

So, unless the root problem is found, or the bug will stay idle (no new "Me too" comments, no new dupes) for considerable time, it should stay "NEW".

*I meant I've met it 4.2.5->4.3.3, of course

Ok Mike, but do you have the chance to check if the bug persists in a 4.2.7 to 4.3.4 upgrade or in a 4.3.3 to 4.3.4 upgrade ?

This bug is actionable if:
1) Reproducible always, e.g. someone says he sees it when upgraded from 4.2.x to 4.3.y, and he can reproduce it any time he wants, and I can reproduce it too in a clean VM.
-- OR --
2) I get the install logs of a bad update, which I requested in comment 35. 

Any other discussions and comments are useless.

I can provide the requested log. The upgrade was 4.2.8 > 4.3.4. The Open Symbol fonf (and many other) vanished during the upgrade. Formula Editor started showing Wingdings after the update. Exactly, the requested case!

The only problem is the log is too long to attach (5.6 MB, almost twice the allowed limit of 3 MB). I'll try to cut it in half.

For now, I can copy all lines containing the opens___.ttf string

It seems the file is being registered. However it is never actually installed!

One last morsel. Uninstalling and installing back 4.3.4 WORKS FOR ME. I also have the log of the install, if needed.

Log of the problematic upgrade

Thanks Mike Kaganski for the (offline) advice of compressing it. It is so obvious that only the hour (1 a.m.) excuses me.

Just for completeness, it is 4.2.8 -> 4.3.4 upgrade on Win 7 32-bits.

I had solved this bug in my previous version and when I upgraded LO to 4.3.5.2 I have to download and install another time the OpenSimbol.ttf
I have Windows 8.1
