End of Word ( hidden Characters ) Perl or C++ ?

Hi
As there is a end of line character when converting say a PDF file to text, is there also a end of word character when converting a pdf to a text file. When the conversion takes place all the words on the same line are bunched together. Is there a way of separating these words ( hence the reason for this question.

Thanks in advance.

 

Use perl , try =~ s/ / /g

 

use EOF
