I apologize (especially to Mike) for the recent problems.
The root cause of the ongoing issues with the past few versions was related to invalid characters in the custom editors. It took some hair pulling to figure this out.
When text is copy and pasted into an html editor there can be characters introduced that are not visible and cause problems when converting everything to a PDF (which uses UTF-8 encoding). Some editors even have a “Paste from Word” button to strip these naughty characters. MS Word has always been an on-going headache for html editors.
Thanks to everyone for your patience and for helping to make this tool even better.
