The CSS WG decided as follows on Björn Höhrmann's comment[1] about  
Unicode (numerical) escapes outside the legal Unicode range:

  - Add this text to 4.1.3:

    If the number is outside the range allowed by Unicode (e.g.,
    "\110000" is above the maximum 10FFFF allowed in current Unicode),
    the UA may replace the escape with the "replacement character"
    (U+FFFD). If the character is to be displayed, the UA should show a
    visible symbol, such as a "missing character" glyph (cf. 15.2, point
    5).

Comments.")



For the CSS WG,

Bert
