This problem has not been attempted before with tesseract.
The biggest thing to watch out for is to skip the text line and word
finding. You might have significant success just running the classifier on
the connected components.
Training might be a bit tricky too, since it relies on the text line
to the previous line or an extra line in
between. I've also observed that sometimes, the same symbol can be
recognized easily when it occurs in a subscript position, but is often
mistaken when it occurs in a superscript position.
