Hi I get the followng error when calling the ConvertHtml method from my code with a HTML string.

If I do a simple test string e.g. "<p>test</p>" it works but with the full complex HTML I need to putput I get the error but can't see where to look to firgure out what I am doing wrong.

This seems to be to do with UTF-8 encoding. When I pass a normal string it works (and has ASCII encoding) but passing the output from a rails view which is UTF-8 it gives the above error.

Hello,

After some googling I found this: https://github.com/jharig23/twilio-test/blob/master/README.md

For now, a workaround should be to convert ActiveSupport::SafeBuffer to String before passing it to convertHTML().
