ok, tried to understand this issue.  problem isolation follows.  this didn't come up for me earlier because typically the example archives don't use commas as whitespace.

am working with test scene at


The following seemed to convert OK with commas inserted, but then saw the problem:

   <Text string='"One, Two, Three","","He said, \"Immel did it!\""'>
	<FontStyle justify='"MIDDLE","MIDDLE"' style='BOLD'/>
	<Material diffuseColor='0.6 0.4 0.2'/>

{ "Shape":
	  { "Text":
		  "@string":["One, Two, Three\",\"\",\"He said, \"Immel did it!\""],
			{ "FontStyle":

conversion console log follows.

I think the json schema is telling us that this is the JSON-output culprit:




the value should be unescaped in the middle, instead appearing as


... thanks for continued testing, i'll work on this case next.

am working to make things handle all legal syntax.  so no adjustment of legal content is desired, that will just hide problems.
