{-}As implementation one could either write such an escape method from scratch
or use the JSON-P Standard
({-}[-https://javaee.github.io/jsonp/).-|https://javaee.github.io/jsonp/)]
The simplest approach is just leveraging {{StringEscapeUtils.escapeJson(...)}}
from Commons Lang3
([https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringEscapeUtils.html#escapeJson-java.lang.String-])
which is already a dependency.

> Add display context for JSON string

> Key: SLING-11538
> URL: https://issues.apache.org/jira/browse/SLING-11538
> Project: Sling
> Issue Type: Improvement
> Components: HTL
> Reporter: Konrad Windszus
> Assignee: Konrad Windszus
> Priority: Major
> Fix For: Scripting HTL Engine 1.4.22-1.4.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> It would be useful to add an output context to HTL to be used inside JSON. As
> JSON is very complex, the most essential one which currently cannot be
> achieved with any other existing contexts is escaping for a JSON String value
> (compare with https://github.com/adobe/htl-spec/issues/5).
> I propose to introduce a new context {{jsonString}} next to {{scriptString}}
> in
> https://github.com/apache/sling-org-apache-sling-scripting-sightly/blob/192d953514e6e579428cda157a7e83fc2a05cc01/src/main/java/org/apache/sling/scripting/sightly/impl/engine/extension/XSSRuntimeExtension.java#L93.
> As it is not part of the official HTL spec at
> https://github.com/adobe/htl-spec/blob/master/SPECIFICATION.md#121-display-context
> it needs to be listed as Sling-specific addition in
> https://sling.apache.org/documentation/bundles/scripting/scripting-htl.html#extensions-of-the-htl-specification.
