Typical picture to AA converter just treats all output characters as pixels, considering only it's overall boldness.
I want Image -> Ascii Art converter that uses OCR technologies and choses characters that are most similar to the parts of input image (even if somewhat displaced). Ideally it should also preserve some text.
Example of conversion (manually done):
__

\_ C
┌------------\

| \ T T
| --------┐
| Hello, world. |

\ ______/
------------------/
Preferably FOSS running on Linux or portable, no budget.
