|| /* Glibc since 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 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 attributes(7).
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.
