I have just investigated this. The documentation for pcre2test was deficient.
Just supplying an empty string cancels any previously set up replacement, but
you can make it substitute an empty string by providing a buffer length so that
the "replace" modifier has a non-empty value. For example:

/xxxx/replace=[4]

I have updated the documentation.
