ObjectARX provides a package of character-handling functions, as shown in the table that follows. The advantage of this package over the standard C library package, ctype.h, is that these functions are independent of any specific character set and are not bound to ASCII. They are customized to the current AutoCAD language configuration. In other respects, they behave like their standard C counterparts.
