Invalid Json caused by characters in the description

[dallinns]

I have a webscript that returns a list of files as json. When a file has a description that has a line break in it then when I try to decode the json on the other side it is invalid. Is there a way to json ecode the description string in the ftl template? or in some other way?

This should suit your needs:

So you'll end up with something like
${description?json_string});
