Hi Chin Khun, That's cool to hear that you're working on reversing this problem which is just on our plan. It should integrate with ocr solution.

I ran into this with early versions of PDFBox (see http://mail-archives.apache.org/mod_mbox/pdfbox-users/201204.mbox/%3ccad2k14ojb02+u+klrtykl6xzou_++f-hvnw6myvh5lroj1l...@mail.gmail.com%3E). I was trying to create characters from PDFBox to pass into Batik and (I thinkPDFBox 1.6) output vectors (curves) instead. Later versions output characters. Of course you will have to translate the SVG into PDF. So I think there are tools which can be chained to solve your problem but you will probably have to spend some time glueing them together. I am working on the reverse problem - trying to discover the characters from their curves (some documents only store the glyphs). That's much harder but it's possible. So really determined people may be able to reconstruct characters from curves (e.g. by writing to a canvas and OCR) but it's a lot of work.
