Test parsing of CSS escapes.

SUCCESS

Rules from the stylesheet:

#a127_\ { color: red; }
#a128_€ { color: red; }
#b128_€ { color: green; }
#a159_Ÿ { color: red; }
#b159_Ÿ { color: green; }
#a160_  { color: red; }
#b160_  { color: green; }
#a384_ƀ { color: red; }
#b384_ƀ { color: green; }
Expected result:

#a127_\ { color: red; }
#a128_€ { color: red; }
#b128_€ { color: green; }
#a159_Ÿ { color: red; }
#b159_Ÿ { color: green; }
#a160_  { color: red; }
#b160_  { color: green; }
#a384_ƀ { color: red; }
#b384_ƀ { color: green; }
