toascii - convert character to ASCII
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.
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.
