.PP
\f[I]Notes:\f[]
.PP
The "%s" specifier takes C string arguments, not ALLEGRO_USTRs.
Therefore to pass an ALLEGRO_USTR as a parameter you must use
al_cstr(3alleg5), and it must be NUL terminated.
If the string contains an embedded NUL byte everything from that byte
onwards will be ignored.
.PP
The "%c" specifier outputs a single byte, not the UTF\-8 encoding of a
code point.
Therefore it is only usable for ASCII characters (value <= 127) or if
you really mean to output byte values from 128\-\-255.
To insert the UTF\-8 encoding of a code point, encode it into a memory
buffer using al_utf8_encode(3alleg5) then use the "%s" specifier.
Remember to NUL terminate the buffer.
