------------------------------------------------------------------
Text extraction always works with the 2.0 version.
Rendering is bad with the 2.0 version. I'm able to render the file properly
with 2.0 by making two changes:
- adding
{code}
dic.setName( COSName.TYPE, COSName.TRUE_TYPE.toString() );
{code}
after the "Substituting TrueType for unknown font subtype=" warning
(I'm not committing this because I prefer to have another opinion. The idea is
that if we are to fake a TT font, that we should attach the type)
- adding a line for Courier-Bold in the PDFBox_External_Fonts.properties file.
was (Author: tilman):
Rendering is also bad.

> Project: PDFBox
> Issue Type: Bug
> Components: Rendering, Text extraction

> Environment: Windows 7
> Also, PASE on IBM i

> I have been using PDFBox 1.8.4 to extract text from several different PDF
> files fine. I use the latest PDFBox app with ExtractText command line.
> There is one PDF that PDFBox (and iText) fails to extract any text even
> though I can extract the text with Adobe Reader and also pdftotext.exe part
> of XPdf. "java -jar pdfbox-app-1.8.4.jar ExtractText Test1.pdf Out.txt". I
> don't want to have to rely on using pdftotext.exe from a PC since this is
> part of an automated application. I think the error relates to an unknown
> font type and having to use the few fonts installed in the jar file. I tried
> running the API classes and trying to force a font from a certain location
> but I still got errors. I thought I loaded the font with the loadTTF method
> but I don't know if that did anything with the font. I would really like to

> Here are the errors I am getting. I tried this from both a Windows 7 PC and
> our IBM i in the PASE environment but I get the same errors. The section
> starting processEncodedText and on repeats a few times so I just included the
> first entries.
