--- Comment #3 from Roman Eisele <b...@eikota.de> ---
Thank you very much for your bug report!
REPRODUCIBLE with LibreOffice 3.6.4.1 (Build ID: a9a0717), German langpack
installed, on Mac OS X 10.6.8 (Intel). As my screenshot shows, LibreOffice uses
for the superscript figures and letters in the axis labels another font
(family) than elsewhere in the chart and axis labels.
While the font family used elsewhere in the chart is Lucida Grande (a Mac OS X
system font), the superscript figures appear
* in Lucida Grande: only superscript 2 and 3
* in some other font (in my case: Alegreya): superscript 0, 4, 5, 6, 7, 8, 9,
i.
The difference between these two groups of figures is that the superscript 2
and 3 are part of the basic ISO Latin 1 character set, and therefore are
located in the “Latin-1 Supplement” section of Unicode at U+00B2 and U+00B3,
but the other “superscript figures and the superscript i are located in the
“Superscript and Subscript” Unicode section at U+2070 and following.
It seems that LibreOffice takes the superscript 2 and 3 from the main text font
(here: Lucida Grande), but what regards the extended superscript letters (which
are missing from many simple fonts) it searches for another font which contains
these special characters, and then takes the glyphes for these letters from the
1st font which contains glyphs for them -- in my case, this is Alegreya.
This behaviour would be entierly correct *if* the extended superscript letters
0, 4, ..., 9, i would be missing from Lucida Grande, just like they are missing
from many simple fonts. Then LibreOffice would *need* to take these letters
from some other font. But -- and this is IMHO the real bug -- Lucida Grande
*does* actually contain glyphs for the superscript 0, 4, ...., 9 and i. So
LibreOffice does change the font without any necessity. And this is a bug.
