Ok, a quick bug fix update, 0.4.0. It's in the update feed so you should get it automatically.
- I reworked how parameters are passed to web2lrf under NT. This should fix the URL mangling issue.
- I added a filename override field to the options dialog. Unicode file names are still not working under NT, I think this is a python/NT issue, but I'm still researching it. In the meantime if you create a book with a Unicode title use the override field on the advanced tab to give it an ANSI file name; e.g. myfile.lrf.
