------------------------------------

             Summary: Sightly: StyleString context doesn't properly escape
                 Key: SLING-4177
                 URL: https://issues.apache.org/jira/browse/SLING-4177
             Project: Sling
          Issue Type: Bug
          Components: Scripting
            Reporter: Vlad Bailescu
            Priority: Minor
             Fix For: Scripting Sightly Engine 1.0.0


The {{context='styleString'}} expression option seems to escape strings the same way as {{context='scriptString'}}, but this breaks the string, making that context unusable. CSS strings are to be escaped {{\HH}} and not {{\xHH}} like in JS:
https://developer.mozilla.org/en-US/docs/Web/CSS/string

Consider following example:
{code:html}
<style>
.ft:after { content: "${'\'' @ context='styleString'}"; }
.in:after { content: "${'\"' @ context='styleString'}"; }
</style>
{code}

Which currently gets incorrectly rendered as follows:
{code:html}
<style>
.ft:after { content: "\x27"; }
.in:after { content: "\x22"; }
</style>
{code}

Following output would have been expected:
{code:html}
<style>
.ft:after { content: "\27"; }
.in:after { content: "\22"; }
</style>
{code}
