(I'm sorry that I couldn't do anything for a few days)
Pdfbox can't extract the diagonal texts. I had a test today, too.
1. The content of my pdf file is like this:
!image-2018-07-31-23-38-32-829.png!
2. My test program is as follow..
PDDocument doc = null;
try
{ doc = PDDocument.load(file); PDFTextStripper parser = new
PDFTextStripper(); String text = parser.getText(doc);
System.out.println(text); }
finally
{ if (doc != null) doc.close(); }
3. The results are as follow..

PDFTextStripper extracts only texts rotated 90, 180, 270 degrees.
PDFStreamEngine.showGlyph(...) is same.

PDFStreamEngine.showGlyph(...) does also.
