FreeMarker defines a default node handler for text, but it should be
overridden if you generate XML or HTML, for the reason you said...

As you might know #escape only affects the ${...}. What is important
to realize that it affects only those ${...}-s that are between the
<#escape ...> and </#escape> in the template source code (not on
runtime). With other words, #escape is a pre-processor directive that
affects the template itself, and has no direct runtime effect. So
#escape doesn't influence how text nodes are printed, unless the
source code of the macro that handler the text node is inside the
#escape, again, in the source code. So, you should have one of these:

  <#escape x as x?html>
    ...
    <#macro @text>${.node}</#macro>
    ...
  </#escape>

and

  <#-- No #escape around -->
  <#macro @text>${.node?html}</#macro>
