Why do you use a lower case letter for the hex value 'a'?  The Unicode
standard exclusively uses caps.  In a few years, there might be
automatisms for Unicode handling; these will of course match the
standard exactly.

If you look long enough at this picture you'll detect that the
characters are not on a quadrangle, but on a circle - and now the circle
starts turning, turning, ... - stop it!  Well, unfortunately, computer
stream handling is only linear, whereas nice squared circles have 2
dimensions.  So to get in terms with the computer psychology the macros
could calculate the decimal value of the character code and print that
many U+2623 (BIOHAZARD SIGN) characters in a single row.
