Dump blocks as text

Is there a way to dump the blocks into text (not PNG)?

Namely, you will get a text file as if you arranged the blocks vertically, expand them all, clean up, download blocks as PNG and apply a (very) good, color insensitive OCR to it :)?

(i.e. did someone parsed the aia's BKY part...)

No.
