16 Notes:
17
18 The “%s” specifier takes C string arguments, not ALLEGRO_USTRs. There‐
19 fore to pass an ALLEGRO_USTR as a parameter you must use al_cstr(3),
20 and it must be NUL terminated. If the string contains an embedded NUL
21 byte everything from that byte onwards will be ignored.
22
23 The “%c” specifier outputs a single byte, not the UTF–8 encoding of a
24 code point. Therefore it's only usable for ASCII characters (value <=
25 127) or if you really mean to output byte values from 128—255. To
26 insert the UTF–8 encoding of a code point, encode it into a memory buf‐
27 fer using al_utf8_encode(3) then use the “%s” specifier. Remember to
28 NUL terminate the buffer.
