## This is a wrapper script for sending documents to Docverter
## for conversion from markdown to PDF using Pandoc. Typically
## Docverter calls are made with cURL; this script uses httplib.
## It is intended for use with Pythonista on iOS, so output file
## is uploaded to Dropbox after document conversion.
## For more information, see: http://www.docverter.com/api.html

This script is truly great! The only problem is that you can't have any non ASCII characters in your markdown (for example the Swedish letters å, ä and ö). Any idea of how to fix this?

Thanks in advance!

Found it myself. "input_text.encode('ascii', 'xmlcharrefreplace')" seems to do it.

input_text = clipboard.get()
input_text = input_text.encode('ascii', 'xmlcharrefreplace')
f = open("docverterin.txt", "w").write(input_text)

With the new version of Pythonista the "Open in..." function is a better solution to the above mentioned problem, since you don't have to write the text file again and mess up the Unicode. It also makes the workflow more smooth.
