review the 2 slides to graphically explain the issue

Here is the problem.  When a .pptx is created in powerpoint and opened in Libre, the immediate line following a superscript for a date is also converted to superscript.  
Additionally, when a .pptx file containing superscripts is created in Libre, the position is a lot higher than it should be when it is opened in Powerpoint. 
I have attached a .pptx file with screen captures showing what I am trying to explain.

Thanks for reporting this issue. Confirmed under GNU/Linux using:

v4.2.6.3 Build ID: 3fd416d4c6db7d3204c17ce57a1d70f6e531ee21
v4.3.2.2 Build ID: edfb5295ba211bd31ad47d0bad0118690f76407d

... and under Win7HP using MSO2007. In a presentation saved as PPTX superscript characters in either the slide title, slide text, or a list item are rendered too high, when opened by MSO2007.

Please report this issue in a separate bug report as this deals with a PowerPoint-generated file.

As per comment 1 status set to NEW. Also tested under GNU/Linux using:

v3.3.4.1 OOO330m19 Build: 401
v3.4.6.2 OOO340m1 Build: 602
v3.5.7.2 Build ID: 3215f89-f603614-ab984f2-7348103-1225a5b
v3.6.7.2 Build ID: e183d5b
v4.0.6.2 Build ID: 2e2573268451a50806fcd60ae2d9fe01dd0ce24
v4.1.6.2 Build ID: 40ff705089295be5be0aae9b15123f687c05b0a

It appears that superscript characters were not supported at all in v3.3-3.5 (content fails to display), in v3.6-4.0 the characters are not set in superscript, and in v4.1, v4.2, and v4.3 they are displayed too high.

Summary amended for clarity. Version set to 4.1.6.2. Platform to All/All.

** 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 (5.0.1 or preferably 5.0.2.2 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. If the bug was not present in 3.3 - add "regression" to keyword
