Description

If read was done using WINDOWS-1252 charset and writing is done using
UTF-8 then resulting PDF will be broken after load and save operations.

PDDocument document = PDDocument.load(sourcePath);
document.save(targetPath);

If source PDF contains XObject dictionary reference whose name isn't
encoded in UTF-8. For example.

/L#f8vetann 16 0 R

That is read using WINDOWS-1252 encoding. Now if write operation is
using UTF-8 then the resulting name will be

/L#3Fvetann 16 0 R

And resulting PDF is broken and image is missing.
