Stripping HTML from the message body returned by a rest call

I often want to truncate the message body returned by a REST call - sort of like making my own teaser.  This quick little freemarker code will clean out any HTML (so I don't end up with unclosed tags...

Here is a problem:

What if I want to limit the subject title to 50 characters, and in the subject title, there happen to have html entities like < & ™ "

When you truncate the string, you may accidentally cut html entities in half, eg. "&am"

 

What is the freemarker function to use to convert html entities into normal text? From the rest api, they all return subject title as html, eg: "2 > 1" is actually "2 > 1" in the rest api response.

 

${utils.html.stripper.from.gdata.strip("<p>hello <b>world</b><strong>!</strong>")}

The above freemarker snippet works.

Do we have any docs of the full utils object?

    I found a work-around. eg. subject title char limit = 50.

    After truncation, I can do another check by using string?last_index_of to locate the &

    If & is too close to the end of the truncated string, then do another substring to remove anything from & to the end.
