return ::isspace( cc & 0xff );
// Warning: we are using UTF8 char, so values are coded from 0x01 to 0xFF
// isspace( int value ) works fine under Linux,
// but seems use only a 7 bits value under mingw, in comparisons.
// (for instance 0xA0 is seen as 0x20)
// So we need to test if the value is ASCII ( <= 127) and a space ( ' ', \t, \n ... )
// and not just a space:
return ( (unsigned) cc <= 127 ) && ::isspace( cc );
