The best fix is to tell them not to do this.

With XSLT 2 you can use analyze-string or substutute(),
but with XSLT 1 you can do a (recursive) loop with
contains() to look for the string to replace.

A recursive template might take two parameters,
input and input-processed, as well as
$string (the thing to replace) and $replacement

choose
    when $input is empty
    return $input-processed

    when $input contains $string
    call self with
       input-processed = concat(substring-before($string), $replacement)
       input = substring-after($string)

    otherwise
    return concat($input-processed, $input)
