Version 1.4 to 2.0 changes
OCR engine changes
- The engine recognises the Euro symbol and accented characters (version 2 characters). (This depends on the licence you have installed. If you have a standard licence installed then you will get a 100 A4 page trial of the higher characters, after which the OCR engine will revert to recognising only the version 1 characters)
- Licences are additive. If you purchase two or more licences you can run two or more OCR engines in parallel
- Lex processing now supports, in addition to English: Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish without the need to specify the language in advance
