Note that D's stdlib currently provides no means to do this, not even
on the fly. You'd have to interface with eg ICU (a C/C++/Java Unicode
library) (good luck ;-). But even ICU, as well as supposed
unicode-aware typse or librarys for any language, would give you an
abstraction producing correct results for Michel's example. For
instance, Python3 code fails as miserably as any other. AFAIK, D is the
first and only language having such a tool (Text.d at
https://bitbucket.org/denispir/denispir-d/src/a005424f60f3).
D is not the first language dealing correctly with Unicode strings in
this manner. Objective-C's NSString class search and compare methods
deal with characters with combining marks correctly. If you want to
compare code points, you can do so explicitly using the NSLiteralSearch
option, but the default is to compare the canonical version (at the
grapheme level).

In
Cocoa, string sorting and case-insensitive comparition is also
dependent on the user's locale settings, although you can also specify
your own locale if the user's locale is not what you want.
