The OCR feature of Finereader PDF only recognizes as Greek the Unicode Basic Greek (i.e. monotonic) characters. Polytonic Greek, which in addition to Basic Greek also uses the Unicode Extended Greek characters, is recognized as Basic Greek, for example, ἀ is recognized as α, ἄ is recognized as ά, ἆ is recognized as ά, etc.

This request is that Polytonic Greek is included in Finereader 16 PDF as an alternative language to Greek.

Justification for this request: Polytonic Greek has been the only Greek script up to 1982 when Basic Greek was imposed by law on state documents and education. It is still being used today by several contemporary writers, poets, publishers, the Church, and part of the press. It is also used in education in the context of the study of older texts (ancient, medieval etc).

Anything published in Greek (ancient, medieval or modern) up to 1982 has been exclusively published in polytonic Greek. Therefore any digitization effort of pre-1982 texts necessitates polytonic Greek OCR. 

A polytonic Greek hunspell dictionary is available for integration into Finereader PDF for use in the OCR.
