// Character classification functions

//
|
|
// NOTE: Character classification routines in C standard library
|
|
// (isdigit(), isalpha() etc.) have integer argument instead of char.
|
|
// Therefore if character from extended Ascii part of char table
|
|
// (i.e. above 128) is passed into such functions it is converted
|
|
// to int giving negative value (if characters are signed that
|
|
// is default for most compilers).
|
|
// It can be dangerous since implementation of these C functions
|
|
// may use argument as index in the array without any checks
|
|
// (for instance, in Microsoft VC++ -- see MSDN)
|
|
// To avoid this, we cast char to unsigned char when passing to these functions.
