Task

Given a character value in your language, print its code   (could be ASCII code, Unicode code, or whatever your language uses).

Example

The character   'a'   (lowercase letter A)   has a code of 97 in ASCII   (as well as Unicode, as ASCII forms the beginning of Unicode).

Conversely, given a code, print out the corresponding character.

(formerly Perl 6)
Both Perl 5 and Raku have good Unicode support, though Raku attempts to make working with Unicode effortless. Note that even multi-byte emoji and characters outside the BMP are considered single characters. Also note: all of these routines are built into the base compiler. No need to load external libraries. See Wikipedia: Unicode character properties for explanation of Unicode property.
