Created attachment 70218 [details] Screenshot shows that the wrong font is used for superscript text in axis labels
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.
Thank you for your quick response. The character "1" is also not correct. The fontset Lucida Grande produces "i" instead of "1". Probably due to missing characters in fontset as you described above.

About versions: The bug is still REPRODUCIBLE with a current master build, e.g. LOdev 4.0.0.0.alpha0+ (Build ID: ed8067; pull time: 2012-11-15 03:54:19). The bug is already REPRODUCIBLE with identical results in LibreOffice 3.3.0, OOO330m19 (Build:6), tag libreoffice-3.3.0.4. Probably inherited from OOo (or GoOO). → Adapting Version field to the first version which is known to contain the bug (as usual).
(In reply to comment #4) > The character "1" is also not correct. The fontset Lucida Grande produces > "i" instead of "1". The question if the superscript “i” instead of “1” is a bug or not, depends on how you entered the axis labels. U+2071 is correctly a superscript i (not 1), the superscript i is at U+0089, and if I manually insert U+0089 into the label text, it correctly remains a superscript 1 in Lucida Grande font. So, how did you enter the axis labels text?
At the shown position of the cursor, I would have expected a ''1''. http://dl.dropbox.com/u/16673743/bug_57249.odt Did you get the sample? My MAc uses other replacement characters than yours, so the exponents look terrible.

** Please read this message in its entirety before responding ** To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year. There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present. If you have time, please do the following: *Test to see if the bug is still present on a currently supported version of LibreOffice (4.4.1 or later) https://www.libreoffice.org/download/ *If the bug is present, please leave a comment that includes the version of LibreOffice and your operating system, and any changes you see in the bug behavior *If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a short comment that includes your version of LibreOffice and Operating System Please DO NOT *Update the version field *Reply via email (please reply directly on the bug tracker) *Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case) If you want to do more to help you can test to see if your issue is a REGRESSION. To do so: 1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) http://downloadarchive.documentfoundation.org/libreoffice/old/ 2. Test your bug 3. Leave a comment with your results. 4a. If the bug was present with 3.3 - set version to "inherited from OOo"; 4b.
