Unless you omitted something, that's a really long
and slow way to do this:

 text = container.research[name].read()

Don't iterate over all items when you only care about one of
them and know what it's called :)
But that's not your problem...

We don't know what kind of objects you have. But this sounds like
the code for "object" is lacking some security declarations, and zope
2.7 was too permissive.

Hmm, you never showed us where this text actually gets put into the
page.  In the example you gave, it gets assigned in a <dtml-let>
tag, and that's the last we saw of it.
Perhaps you have something like <dtml-var text html_quote="1">?

If so, remove the html_quote attribute.
