Well, that upside down question mark is due a wrongly formatted MathML code.
Your formula is:
matrix {# {italic "G"_italic "x" = left [ matrix {{-italic "1"} # italic "0" # italic "1" ## {-italic "2"} # italic "0" # italic "2" ## {-italic "1"} # italic "0" # italic "1"} right ]} # {"(1)"}}
If I just delete the first #, the question mark is gone:
matrix {{italic "G"_italic "x" = left [ matrix {{-italic "1"} # italic "0" # italic "1" ## {-italic "2"} # italic "0" # italic "2" ## {-italic "1"} # italic "0" # italic "1"} right ]} # {"(1)"}}
I'm not a MathML syntax expert, but I guess the formula was just incorrectly formatted?
Kind regards,
Joren
I can't see anything wrong with the MathML file. It looks like the first empty element before '#' sign is caused by miss parsing the mspace element in the MathML file. The formula editor can ignore the first mspace or add '`' for spacing in the converted equation. (In reply to comment #2) > I can't see anything wrong with the MathML file.

We could try to avoid this problem but, this seems to be a formula problem.

Maybe I can try to look at this in this week (I'm really busy, but, I can take a look....) |
