Thanks Lorna and David for this information. I was not familiar with ABBYY
FineReader. I have been impressed with use of OmniPage OCR for some kinds of
text (in English mainly; occasionally French) that I expected problems with,
due to the quality of the originals and the fact I had to scan photocopies.
Getting at least as good or better performance in FineReader with at least
some extended Latin would be impressive.
One hopes to see an expansion of the extended Latin character repertoire to
cover languages with multiple diacritics (noting the absence of, among
others, Yoruba and Igbo in Africa, and Vietnamese in Asia).
Part of the reason for the question is a discussion about ways to promote or
develop a project on digitization of African language materials. Ideally one
should OCR right the first time, and if the technology permits that for
extended Latin orthographies, that's one less problem to overcome.
All the best.

Quoting two different colleagues of mine: "I recommend FineReader
(www.finereader.com) from Abbyy Software. While OmniPage is good, FineReader
is better--the best OCR software at an affordable price...FineReader can
handle special characters better than other OCR programs."
"I heartily recommend FineReader. It can be "trained" to recognize
speciality characters, and it is surprisingly accurate - about 99% - which
means that 1% of the document will require manual corrections."
