"Many" and "several" is not proper bug reporting. Not immediately clear with
66-slides test file. 

>From what I see in 6.2+ on slide 7, there's still wrong square root with
original test file, but it's correct on attached slide 7 PPTX extracted in MSO.

As Wikipedia, Microsoft Equation Editor is simplified version of MathType, so I
think these equations can be edited by both Microsoft Equation Editor and
MathType. As of MS Office 2013, if you want to just install this editor, you
can click “Custome” key to select “Equition Editor” only.

In case there is a font problem in addition for you, goto
http://www.dessci.com/en/dl/fonts/?src=hpfnt, where Design Science describes,
how to get the fonts needed for MathType.

--- Comment #9 from Regina Henschel  ---
The equations are not created with Microsoft Equation Editor but are OLE
objects of "MathType 5" a product of Design Science (www.dessci.com).

So LibreOffice leaves them as OLE object and shows the replacement graphics.
That has worked correctly for most equations in Version: 4.2.2.1
Build-ID: 3be8cda0bddd8e430d8cda1ebfd581265cca5a0f. Only few equation have some
errors in position.

It is partly broken (some images are correct, some are distort) in Version:
4.3.0.0.alpha1+
Build ID: 145f2e970f46a3a3e5456b122d71f17c3abe878f
TinderBox: Win-x86@42, Branch:master, Time: 2014-04-26_23:32:36

It is totally wrong in Version: 4.4.0.3
Build-ID: de093506bcdc5fafd9023ee680b8c60e3e0645d7
Gebietsschema: de_DE

It makes no difference, whether in Options > Load/Save > Microsoft Office the
converting options are checked or not.

Because I run all versions on the same PC, and so the same fonts are available,
the reason cannot be a missing font.

Microsoft Equation Editor can save the font styles into equations. In this file
you can found them in the path /ppt/embeddings if you open this file by 7-zip.

MT Extra used by Equation Editor

Microsoft Equation Editor also used MT Extra font to display certain symbol,
which is also has its own character encoding. This font generally installed in
C:\Program Files\Common Files\microsoft shared\EQUATION if you installed
Microsoft Office.

Font setting of Microsoft Equation Editor

On Microsoft Equition Editor the font of Greek letters and mathmatical symbols
are defalting to “Symbol” font, which has own encoding. For example, on LO
Writer, when you input the following letters, switch to “Symbol”, they will

It seems to me they are display via “Symbol” font.

I see it messed up in a different way in 5.3, but still messed.
The problem is with theta and phi.
In 3.6 the theta and phi are substituted with q and j and there is no mess.

I guess we can call this some sort of a regression.
