Public bug reported:

Regular expressions like:

  [\s-A]
  [A-\w]

i.e., those that involve non-single-character-escapes inside character
ranges are illegal according to "XML Schema Part 2: Datatypes Second
Edition: F Regular Expressions." ICU either does not consider this an
error or does not catch it. The Zorba code that translates XQuery
regular expressions into ICU regular expressions also doesn't check for
it -- it's non-trivial to do.
