The EI keyword defines an operator for ending the image data. When the stream contains the same sequence, the parser treats that as an end of the image data. As a result, the image and the following content cannot be properly parsed and there is missing content when the document is visualized.

The current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, a mechanism for importing documents with invalid offsets for the objects inside the stream can be implemented.

In PDF, symbolic font programs, such as ZapfDingbats, have built-in encodings that are usually unique to each font, and ordinary their encoding cannot be overridden. When importing a document using a symbolic font with defined encoding, which overrides the build-in encoding, a KeyNotFoundException: 'The given key was not present in the dictionary.', is thrown.

An implementation of JPXDecoder should be created to allow the decompression of data encoded using the wavelet-based JPEG2000 standard.
Guidelines of how to provide a custom implementation of the JPXDecode filter can be found in the Customize Rendering section of the documentation and a sample implementation can be found in the SDK examples.

German umlauts (the characters 'Ä', 'Ö', 'Ü', 'ä', 'ö' and 'ü') will not be printed to a generated pdf file, but the other German "special" character "ß" works.
I use the trial version via the Telerik NuGet feed. A test program and my locally generated file are attached.
