Andreas Lehmkühler reopened PDFBOX-833:
---------------------------------------
I can confirm that the fix introduced a regression with the text extraction as
described by simon -> reopened
> Wrong encoding with Type1C font when specific encoding is defined
> -----------------------------------------------------------------

> Key: PDFBOX-833
> URL: https://issues.apache.org/jira/browse/PDFBOX-833

> The Type1C font implementation overwrites the encoding() method of PDFont
> base class. This results in a lookup of codes to characters as defined in the
> font.
> However if an encoding is explicitly given (like WinAnsiEncoding) this leads
> to wrong results if encoding codes do not match glyph codes.
> In a test document (which unfortunately I cannot make public - an article
> from Elsevier) a Type1C font is embedded which defines a copyright sign at
> glyph position 259. The encoding is defines as WinAnsiEncoding. Text
> characters are defined corresponding to the WinAnsiEncoding. In case of the
> copyright sign it is 0xa9 (169) where the font has glyph 'quotesingle'
> defined.
> Since currently I have no other test cases I implemented following workaround
> for WinAnsiEncoding (which might be relaxed to other PDF encodings as well:
> in PDType1CFont.encode() I start with:
> if ( getEncoding() instanceof WinAnsiEncoding )
> // use PDFont encoding
> return super.encode( bytes, offset, length );
> This resolves the encoding problems for text extraction.
