  From the original code, the following characters are removed:

    U+2011 (non-breaking hyphen)
    U+202F (narrow non-break space)
    U+2044 (fraction slash) 
    U+200B (zero width space)
    ...... (bidi formatting control characters)

  U+2011 and U+202F are non-breaking, U+2044 is a Sm character,
  U+200B is a non-visible space, wrapping after it would make
  this space visible, bidi should be done using HTML features
  and the characters are neither Px or Zx.

  The following Unicode 3.0 punctuation characters are added:

    U+2048 (question exclamation mark)
    U+2049 (exclamation question mark)
    U+204A (tironian sign et)
    U+204B (reversed pilcrow sign)
    U+204C (black leftwards bullet)
    U+204D (black rightwards bullet)
    U+3030 (wavy dash)
    U+30FB (katakana middle dot)
    U+FE63 (small hyphen-minus)
    U+FE68 (small reverse solidus)
    U+FF3F (fullwidth low line)
    U+FF5B (fullwidth left curly bracket)
    U+FF5D (fullwidth right curly bracket)

  Other additional characters were not included in Unicode 3.0.
  The table is based on Unicode 4.0. It must include only those
  characters marking a wrapping point, "before" if the general
  category is UCPS or UCPI, otherwise "after".
