C Language Features
3.12.3.1 The #pragma jis and nojis Directives
If your code includes strings with two-byte characters in the JIS encoding for Japanese and other na-
tional characters, the #pragma jis directive will enable proper handling of these characters, specif-
ically not interpreting a backslash, \, character when it appears as the second half of a two byte
character. The nojis directive disables this special handling. JIS character handling is disabled by
default.
3.12.3.2 The #pragma printf_check Directive
Certain library functions accept a format string followed by a variable number of arguments in the
manner of printf(). Although the format string is interpreted at runtime, it can be compile-time
checked for consistency with the remaining arguments.
includes the directive #pragma printf_check(printf) const to enable this checking for printf().
You may also use this for any user-defined function that accepts printf-style format strings. The
qualifier following the function name is to allow automatic conversion of pointers in variable argu-
ment lists. The above example would cast any pointers to strings in RAM to be pointers of the type
(const char *)

This directive enables this checking for the named function, e.g. the system header file <stdio.h>
