Thanks, that will be helpful.

Seems like our mode "0" with the OpenSymbol rework at OOo 3.3. caused a lot of
issues--encouraging direct entry of "%iSYMBOL" or {italic SYMBOL} formatting.

But then, the mode "1" alternative of all italics (for lower & upper case
SYMBOLs) has continued to function, but also had issues of needing to use
nitalic format.  

With return of  mode "2"--with lower case sybols to italic, and upper case
nitalic--we could really offer the most generally appealing/appropriate default
for handling Greek symbols in StarMath markup.

And if we were to set a mode "2" default, doing it now at the 5.2.0 release
would be the perfect time. It has been missing since 3.5 releases, and would be
reasonable as a reintroduced feature, coupled with a new default behavior for
the Formula Editor.

For handling existing documents, it looks like in
https://bz.apache.org/ooo/show_bug.cgi?id=113276#c12 Thomas Lange had provided
a basic script for converting the StartMath in existing documents to match the
selection made for GreekCharStyle mode. Expect it needs a little clean-up, but
something similar could be provided for users to offer a reformat of the
StarMath to match a change in mode of the GreekCharStyle property. Would avoid
a lot of hand editing of the content.xml of the OLE formuals or ODF Formula
documents.
