Customize special characters to encode?

[jaslong]

We have a use case where we'd like to write JSON into HTML attributes, and we'd like to use html-entities to do this safely.

One problem is that encoding JSON makes it very hard to read since all quotes are encoded.

<div data-user="{&quot;name&quot;:&quot;Conan O&#39;Brien&quot;,&quot;age&quot;:99}"></div>

If we could skip decoding the double quote...

<div data-user='{"name":"Conan O&#39;Brien","age":99}'></div>

Do you think a change to customize the regexp of encoded characters makes sense? Alternatively, you could convince me that this is a bad idea :)
