It isn't a data problem. Perl thinks he/she is trying to take the
reference of the item returned by a call to the function x[1] with a
malformed hashref (not an even number of list items). This is because
the \x{} construct is only valid in strings. He/she also has a
problem in that the \x{} does not interpolate values, it requires a
hexadecimal constant. The right answer is the use hex to get the
decimal value of the hexadecimal string he gets from the regex (which
you rightly point out needs to have guards) and to feed that decimal
value into the chr function to get the UNICODE character he/she is
looking for.
1. If a function x had existed he/she would have gotten a completely
different error message (i.e. the one about the malformed hash).
