TOASCII(3) Linux Programmer's Manual TOASCII(3)
toascii - convert character to ASCII
#include <ctype.h>
int toascii(int c);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
toascii():
_XOPEN_SOURCE
|| /* Glibc since 2.19: */ _DEFAULT_SOURCE
|| /* Glibc <= 2.19: */ _SVID_SOURCE || _BSD_SOURCE
toascii() converts c to a 7-bit unsigned char value that fits
into the ASCII character set, by clearing the high-order bits.
The value returned is that of the converted character.
For an explanation of the terms used in this section, see

SVr4, BSD, POSIX.1-2001. POSIX.1-2008 marks toascii() as
obsolete, noting that it cannot be used portably in a localized
application.
Many people will be unhappy if you use this function. This
function will convert accented letters into random characters.
