[xquery-talk] XQuery and \w, \W in regex (Saxon 8)

[David Sewell]

Given this code:

  let $string1 := '"quoted"'
  let $string2 := "“quoted”"
  return
  ( replace($string1, "\W", ""),
    replace($string2, "\W", "")
  )

Saxon 8.6b returns

  quoted
  "quoted"

(where the " " in the second line are Unicode curly quotation marks).

Is this a bug in the regex handling? U+201C and U+201D should be treated
as separators, no? (Likewise single curly quotes, U+2018 and U+2019; I
haven't tried other punctuation in that code block.)
