You write
"\u{00a9 00a9 00a9}"
The \u{..} format only represents a single character, so you should
only put a single hexadecimal number in there. That number can have a
length from 1 to 6 digits, e.g.,
"\u{a9}\u{00a9}\u{0000a9}"
It's rarely shorter than plain \uXXXX, but you can represent
characters outside the basic multilingual plane (i.e., with code
points above 0xffff).
Example:
"\u{1F4A9}"
