There is nothing in phobos to even change case correctly!
Both are limited if you care about certain stuff like
non-latin based languages like Turkic.
A general toupper/tolower for Unicode is doomed to fail. As
already mentioned Turkish has its specificity, but other
languages also have traps. In Greek toupper/tolower are not
reversible i.e. `x.toupper.tolower == x` is not guaranteed .
Some languages have 1 codepoint input and 2 codepoints as
result (German ß becomes SS in most cases, capital ẞ is not the
right choice in most cases).
etc. etc.
That's why you should implementat formatting providers for
languages that handle such things.
Like in C# you have the CultureInfo class that you can give to
methods such as ToString, ToLower etc. which will correctly
handle specific "cultures"
It's one thing D really misses, but is really hard to implement
when it wasn't thought of to begin with. It should have been
implemented alongside functions that may change between languages
and cultures.
