Greek characters are not displayed correctly(Math)

Asked by Thomas D.

Hello,
I tried to write some formulas for math course recently.
Every time I write "%THETA" (or any other %... special character) in the formula box there is only a rectangle instead of the greek theta character.
If I check the characters in the catalogue window all characters in the "Greek" and "iGreek" set are shown as rectangle.

From one moment to another all special %... characters seem to be corrupted.

I'm running Ubuntu 10.10 32bit and LibreOffice 3.3.2 from PPA-Repositories.

You are missing fonts. LibreOffice documentation and the fonts recommended are ttf-dejavu and artwiz-fonts. Use the Software Center to download and install ttf-dejavu.

Thanks for the fast answer.
The package ttf-dejavu is already installed.
I couldn't find any artwiz-fonts that I could install.

Did that work? I don't have artwiz-fonts either and LibreOffice Math works fine.

When you told me to install that font it was already installed. So the problem persists although the font (ttf-dejavu) is installed.

Just to make clear what I mean with rectangles:

This is a very familiar picture. Those rectangles are definitely caused by missing fonts or by a configuration that loads the wrong font. I probed my installation a bit more.

Bring up LibreOffice Math. Use the Format > Fonts menu option. Hit the Default button. Does this help? On my system, it says that the fonts getting used for math is unexpected:

Formula Fonts:
Variab les: Times New Roman, Italic
Functions: Times New Roman
Numbers: Times New Roman
Text: Times New Roman

Custom fonts:
Serif: Times New Roman
Sans: Arial
Fixed: DejaVu Sans Mono

I should have asked: what Ubuntu version you are running? What is the version of LibreOffice?

My fonts are set exactly the same.
The "Default"-Button just asks me whether I want to save the current settings as default, but does not reset them to default.

I'm running Ubuntu 10.10 32bit and LibreOffice 3.3.2 from PPA-Repositories.

I'm running Ubuntu 11.10 64 bit and LibreOffice 3.4.3. I think you will need to upgrade LibreOffice. https://bugs.freedesktop.org/show_bug.cgi?id=34636 records a bug in 3.3.1.

https://bugs.freedesktop.org/show_bug.cgi?id=42172 records a similar bug in 3.4.3 RC1 on Windows. So, never switch operating systems.

Do you know whether that newer version will put into those PPA-Repositories in the near future?
Otherwise I probably have to install LibreOffice in that newer version manually, do I?

Thanks a lot for your help so far!
