Send an email from a text variable

Emails use HTML formatting, which inherently ignores basic line breaks (i.e. the char(10) and char(13) characters or any combination of the two).  You would need to write functionality to find and replace any char(10) linebreaks with the html equivalent, "<br/>".  While you're at it, it's also a good idea to sanitize 3 other problematic characters - "<", ">", and "&", each of which should be replaced by their HTML equivalents.

What I've gradually come up with is a "sanitization" expression rule that usually looks something like this:

a!localVariables(
  local!characters: {
    "&",
    ">",
    "<",
    char(10),
    char(13)
  }, /* the ordering of these is important. */

  local!replacements: {
    tohtml("&"),
    tohtml(">"),
    tohtml("<"),
    "<br/>",
    ""
  },

  reduce(
    fn!substitute,
    trim(ri!input),
    a!forEach(
      local!characters,
      {
        fv!item,
        local!replacements[fv!index]
      }
    )
  )
)

Thanks it is what I want. The only problem is that when you try to put more than one space (like tab), it dosn't show in the email. Here I show you an example:

The a!paragraphField

The email:

Thank you very much for your answer!

HTML also inherently ignores multiple consecutive spaces.  However my function above uses trim() on the input which would have the same effect.  I'd say remove the trim() command from the above code and see if that improves anything on your end (i'm not 100% sure one way or the other).  If that doesn't work, you could probably also add another character to the "replacements" list for the "space" character and replace it with the HTML equivalent, which, off the top of my head, is something like "&nbsp;" ... though you might need to look that one up to verify.

It works! Thanks a lot! 

And yes, the html code is "&nbsp;"
