Handling greek-like characters in Google Document AI (OCR ) with java

While working with Google Document AI for text extraction (OCR), i encountered an issues:

Sometimes the OCR returns characters that look correct, but actually belong to a diferent alphabet.

For example

image

Or in other cases:

ORIGINAL: ELIZABETH

After converting to lowercase: elizaβετη

Do you have any tips to homologate these cases?

code:
        GoogleCredentials credentials = getGoogleCredentials();



        DocumentProcessorServiceSettings settings =

                DocumentProcessorServiceSettings.newBuilder()

                        .setEndpoint(endpoint).

                        setCredentialsProvider(FixedCredentialsProvider.create(credentials))

                        .build();



        try (DocumentProcessorServiceClient client = DocumentProcessorServiceClient.create(settings)) {



            String name = String.format("projects/%s/locations/%s/processors/%s", projectId, locationId, invoiceId);



            ByteString content = ByteString.copyFrom(image);



            RawDocument document =

                    RawDocument.newBuilder().setContent(content).setMimeType(extension).build();



            ProcessRequest request =

                    ProcessRequest.newBuilder().setName(name).setRawDocument(document).build();



            log.info("Send request google cloud");

            ProcessResponse result = client.processDocument(request);



            Document documentResponse = result.getDocument();

            String value = null;



            for (Document.Entity entity : documentResponse.getEntitiesList()) {

                if(entity.getMentionText().isEmpty()){

                    value = entity.getNormalizedValue().getText();

                } else {

                    value = entity.getMentionText();

                }

                info.put(entity.getType(),value);

            }
