 // 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.
