Recognizing symbols that are not included in the alphabet of a language


Can FineReader PDF recognize text that contains unusual symbols (pictograms, the © and ® symbols, etc.)?


FineReader PDF can be trained to recognize all Unicode symbols. To recognize text with uncommon Unicode symbols, please follow the instructions below.

1. Create a new language and add all the necessary symbols to its alphabet:

  • Open a document in the OCR Editor of FineReader PDF.
  • Go to the Tools menu > Options... > Languages.
  • Click the New button.
  • Select the language of the text that needs to be recognized as the base language and click OK.
  • Click the ... button next to Alphabet.
  • Select and add new symbols to the new language and click OK.
  • Enter the name for the new language and click OK.

2. Train FineReader to recognize the new symbols:

  • Select the new language as the language of the current document.
  • Go to Tools > Options... > OCR.
  • Select the Use training to recognize new characters and ligatures option. Tick the Also use built-in patterns option.
  • Click OK.
  • Click the Recognize button to start recognition.

Note: This article corresponds to FineReader PDF for Windows. If you have the same question regarding the FineReader PDF for Mac program, please consult the article: Recognition of non-standard symbols in FineReader PDF for Mac.

    Where is the "read button"?  The last step implies we know what it is, but I haven't run across it.  I see a button for recognize.

    I'm trying to teach Abbyy Finereader 15 to recognize polytonic Greek. After pressing . . . I don't see any way to insert a new symbol. What am I doing wrong?

    I have the same problem as Michael Abernathy, when I create a new language, I do not have the alphabet button but if I click on the "properties" button, I access the "group of languages properties" window and then, I click the "advanced" button. I access a set of characters but on I click on a new character that I would like to add, nothing happens... Is it a bug? How should I proceed then?

    Thanks in advance!
