You can begin your journey to the guts of Tesseract from the TessBaseAPI::MakeTBLOB() function. Its result then can be used e.g. in LearnBlob() from "blobclass.cpp" or TessBaseAPI::RunAdaptiveClassifier()
However, if you say you have curves besides line segments, you need to restore your glyphs in the bitmap form and then run the training/recognition in a usual way. This is because afaik Tess doesn't support curve approximations of glyph outlines, it only uses straight segments. Or, to do this programmatically, you might use the MakeTBLOB()/RunAdaptiveClassifier() approach.
