Just use the XML UnEscape method.

Who knows why we do the things we do? These little methods will grab the current selection and clipboard it into a new document after base64 encoding or decoding it. Note that the decoding is dumb and will not check that the decoded text is ok to paste into a PN document (i.e. it may very well crash PN -- has not done it to me yet, but I have not been testing with binary files). base64utils.py: <pre><code>############################################################################### ## base64Utils.py -- PyPn utility script to encode and decode base64. ## tested on Python 2.6.1.
