Expose pdf.js getTextContent method for a pdf page

[yveszoundi]

Could it be possible for you to expose the getTextContent method via let's say a Content property to get easily a page raw text?

Use Case

• The developer needs to generate a PDF via let's say PhantomJS for example.
• Inside the PDF file, specific text content needs to be extracted.
• When accessing data.Pages via the pdfParser_dataReady callback, the developer could grab a page text Content promise for further processing, instead of dealing with text.R[0].T manipulations(loops, encoding, etc.). pdf2json is invoked from phantomJS via a node.js sub-process.

Proposed Implementation Add a Content property in pdf.js.

var page = {Height: pageParser.height,                                                                                                             
                 HLines: pageParser.HLines,                                                                                                                     
                 VLines: pageParser.VLines,                                                                                                                     
                 Fills:pageParser.Fills,                                                                                                                        
                 Content:pdfPage.getTextContent(),                                                                                                              
                 Texts: pageParser.Texts,                                                                                                                       
                 Fields: pageParser.Fields,                                                                                                                     
                 Boxsets: pageParser.Boxsets                                                                                                                    
             };                    

If there's another approach that deals with funky characters easily without introducing an API add-on, I'd be glad to hear about it.
