eTFBE can analyse the text and adjust it, report ambiguities and let you type only letters that doesn't look right.
5.1) Create the text file (ASCII or UTF-8) with the original text and layout (newline for each row on the image).
5.2) Open the prepared text file

7.1) If it complain about a problematic character, adjust it as in 6) and 7), then repeat step 5), 5.1), 5.2) etc. until you're done.

Please help me make it better, have a look at it and try to figure out if things aren't working, or behave strange. Let's hear about it in the forum. There are some things that I can't do much about though (load the image viewer the second time one start it), but I appreciate if you have suggestions and/or code snippets to improve it.
