I want to look why the MathML import has become so bad in LO (tdf#75171).
I am also curious about tdf#75171.
It is SmTextNode::CreateTextFromNode() that contains the code putting strange
"italic" on single-letter identifiers when importing a MathML.
Applying the attached patch will stop the behavior (and thus make mmlimport
test cases fail).
Unfortunately the problem is deeper. There should not be any quotes,
because the element <mi> from MathML should be mapped to a variable in
starmath, but actually it is mapped to a text. Removing the italic style
cured only a symptom, the element has still the wrong font and is the
wrong type.
I have compared AOO and LO. They are identic along this way: <mit> -->
XML_MI --> XML_TOK_MIi --> CreateIdentifierContext -->
SmXMLIdentifierContext_Impl. There the member nGroup is explicitely set
to 0 in AOO and in LO this step is missing.
I want to look, whether nGroup and the other members have correct
values. Until now I have done such things using printf, but I thought it
would be good to learn how to use Visual Studio for such purpose.
But I have little idea about why LibO 4.1 was OK while 4.2 and later are NG.
There had been a lot of changes by Frédéric Wang in starmath in quick
succession at that time. I have already looked at them, but not seen
anything obvious.
Kind regards
Regina
