Re: [web-annotation] The textDirection and processingLanguage properties are not needed

@azaroth42 
I think that we have the key for the answer in you question:

> That said, the review did reveal needs that aren't solved by 
unicode. The properties are not only for embedded strings (which in 
JSON we can expect to be unicode) but for arbitrary resources with 
URIs. I have no idea how PDFs store text strings (for example) and how
 well implemented the control characters are in those strings, but I 
can point you to many instances of older or just badly implemented XML
 documents in a huge variety of encodings. As these resources can take
 the role of the body of the Annotation, the unicode proposal isn't 
sufficient to address the requirements.

I see it exactly the opposite. 
One might need to know the text direction for correct representation 
of text embedded in the annotations (TextualBody), not for the correct
 respresentation of external resources.
The external resources must have included inside the 
"files/bitstreams" all information required for a correct 
representation. It is not the responsability of annotations to correct
 wrong html/pdf/xml.
(I might be a usecase for it ... but it is not included in the current
 version of the standard).
