Why do you want brackets around it in the field? If storing multiple values as a list in the same field, note that this is a valid syntax:
SingleWord [[With space]] HelloThere [[Getting Started]]
That is, in a list you only need brackets around tiddler titles with spaces.
A quick followup. The list-ops term in tiddlywiki relates to manipulating titles so that handles the square brackets as needed.

Will give you a link to each title regardless of whether it has spaces in the title or not. You can also do something different with each title inside the list widget.
<$list filter="[enlist{mytiddler!!Myfield}]"/>Will give you a link to each title regardless of whether it has spaces in the title or not. You can also do something different with each title inside the list widget.
