Typoscript - Use regex replace on field value

Question

A part of a COA I have gets the page title. What I would like to do is replace the space between the last two words with a  

But adding the stdWrap.replacement part results in no output at all:

stdWrap.cObject = COA
stdWrap.cObject {
  10 = TEXT
  10.field = title
  10.htmlSpecialChars = 1
  10.wrap = <h2>|</h2>
  10.stdWrap.replacement {
    10 {
      search = \s(\S+)$
      replace = &nbsp;\1
      useRegExp = 1
    }
  }
}

查看Typo3 replacement docs：

10 {
  search = #(a )CAT#i
  replace = \1cat
  useRegExp = 1
}

#中的#(a )CAT#i为regex delimiters。所以，你需要的只是提供任何，比如说：

search = /\s(\S+)$/
