DocSplit fails to extract text on Windows when filenames have spaces

Docsplit invokes pdftotext to extract text, escaping spaces in the filename with \ to construct a command line. On Windows, \ does not escape spaces.

In my instrumented test, docsplit attempts to execute the following command:

pdftotext -enc UTF-8 test-docs/Ideology\ and\ Climate\ Change.pdf extracted-text/Ideology\ and\ Climate\ Change.txt 2>&1

This fails with the error message below. The following command works:

pdftotext -enc UTF-8 "test-docs/Ideology and Climate Change.pdf" "extracted-text/Ideology and Climate Change.txt" 2>&1

You will need poppler on Windows to reproduce, which is available here: http://www.compgeom.com/~piyush/scripts/scripts.html

This is a Windows CLI related error, you should always use " for a filename containing spaces.
