----------------------------------------------------------------
Thanks. I still see the problem with the new PDFBox2.0.3 too. I have attached
the code I'm using. I put a break point and saw that the Text variable
contained the first parsed character repeatedly. I can also provide the PDF
file I'm using if needed.

> PDFParser tika-parsers-1.13.jar not parsing Japanese and Chinese Characters

> Key: TIKA-2080
> URL: https://issues.apache.org/jira/browse/TIKA-2080
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.13
> Environment: Windows 8.1, jdk1.8.0_102
> Reporter: Kaleb Akalework
>
> I'm trying to use tika to parse PDF files that contain Japanese and Chinese
> characters, but for some reason it does parse it correctly. Every character
> that is extracted is changed to the first letter in the line. For example if
> the document contains 早上好, this, the extracted text will correctly know that
> it has 3 characters but all 3 characters will be 早早早, the last two characters
> are replaced by the gfirst character. This same string is correctly parsed,
> in a word document. The follwoing is what I am using as java sample code
> (Don't forget to change the fdilename)
