+ Specifications tells
+ "If a conversion specifier is not one of the above, the behavior is undefined."
+
+ C99 tells
+ "A conversion specifier consists of a % character, possibly followed by an E or O modifier character (described below), followed by a character that determines the behavior of the conversion specifier.
+
+ POSIX:2001 tells
+ "A conversion specification consists of a '%' character, possibly followed by an E or O modifier, and a terminating conversion specifier character that determines the conversion specification's behavior."
+
+ POSIX:2008 introduce more complexe behavior that are not handled here.
+
+ According to this, this code will replace:
+ - % followed by @ by a %@
+ - % followed by by a %SPACE
+ - % followed by . by a %.
+ - % followed by % by a %
+ - % followed by t by a TAB
+ - % followed by E then anything by '-'
+ - % followed by O then anything by '-'
+ - % followed by anything else by at least one '-'. More characters may be added to better fit expected output length
