>
> When extracting text in a PDF document in which word spacing is achieved by 
> matrix translation, in versions 1.3.x and 1.4 the different words are being 
> merged.
> This situation doesn't happen in 1.2 branch. After investigating a bit, the 
> error was introduced with a refactoring of the PDFStreamEngine class, and is 
> related to textMatrixEnd computation. In 1.2 branch the characterSpacingWidth 
> was added after computing the textMatrixEnd, but in 1.3 (and 1.4) this 
> characterSpacingWidth is preadded to the textMatrixEnd, so the system is 
> unable to detect a new word.
