Currently we are converting all classic ui component to touch ui component.And we are serving JSON response for all authored content using custom json service.
We have noticed one issue/observation with respect to content authored using RTE. When we try to get json response for RTE content we are getting "\r\n" for new line character.This was not happening in classic UI RTE. In older version it only adds "\n" for new line character.My concern is why it is adding that extra "\r" with new RTE. Does new RTE "\n" is being replaced by "\r\n"??
Tested this with fresh adobe instance with no custom project code to check if our custom code is introducing this issue but it is available with OOTB RTE.
Using sling:resourceType = "cq/gui/components/authoring/dialog/richtext".
You can reproduce this scenario by creating one RTE component and access json
