std.ctype is modeled after C's ctype.h. It has functions for operating on

believe that ctype stands for character type, so that makes sense). For

It
only works on ASCII characters (non-ASCII characters return false for
functions like isdigit and functions like toupper do nothing to non-ASCII
characters).
What is your definition for ASCII character?
Most of the <ctype.h> functions (or macros) are locale dependent, see
setlocale() and <locale.h>. And there is the <wctype.h>, too.
While the C standardized ways of doing things might not be most appropriate
approach in D domain, we must not base our design decisions on deficient
analysis. "I just want this text uppercase" is one of the hardest things in
the _world_. The problem is not just the header or package naming.
