.RI "\fBCharacter classification routines\fP"
.br
These functions perform character classification\&. They return true or false status depending whether the character passed to the function falls into the function's classification (i\&.e\&. \fBisdigit()\fP returns true if its argument is any value '0' though '9', inclusive)\&. If the input is not an unsigned char value, all of this function return false\&.

This realization permits all possible values of integer argument\&. The \fBtoascii()\fP function clears all highest bits\&. The \fBtolower()\fP and \fBtoupper()\fP functions return an input argument as is, if it is not an unsigned char value\&.
