Portuguese trained data fails to recognize @

[jgsmarques]

Hi,

I'm using tesseract to perform OCR in a document that contains an email address. Using the eng trained data, it recognizes the email address correctly (but naturally fails in all accented characters). When I switched to the por trained data, it picks up all portuguese characters correctly, but fails to recognize the @ in email addresses. Is there any additional configuration needed for this special characters?

Thank you!

I present the same problem. I try to use multiple languages, but it doesn't work.

#54 describes a similar problem for Turkish. It's likely that the training data for the two languages didn't include any examples of email addresses.

That's correct. See por.unicharset and tur.unicharset which do not contain the @ character. So that character was not part of the training data and will therefore never be recognized by those models.

I suggest to use -l Latin in similar cases.
