Draco_Transcoder not handling escape characters properly

[brian3814]

Hi, I'm trying to compress a glTF model which has node name with escape characters, but it seems to me that the transcoder isn't parsing it correctly.

As shown, the original model can be loaded properly(I'm using three.js editor for testing)

Yet, after compressing with the transcoder, three.js editor failed to load the model and return with following error message, which might be caused by unescaped character.

Expected ',' or '}' after property value in JSON at position 207

I am wondering if I am missing something or there's actually a false parsing?

Thanks.
