This doesn't actually work properly in all languages. It will
probably work in most, but it's not entirely correct.
Ex. Turkish will not work with it properly.
Very interesting article:

Wow, I didn't expect anything like this and just thought that the
nightmares of handling 8-bit codepages for non-English languages
ceased to exist nowadays. Too bad. What are the best practices to
deal with Turkish text in D language?
For example, [Ukrainian letters 'і' and
'І'](https://en.wikipedia.org/wiki/Dotted_I_(Cyrillic)) don't
share the same codes with Latin 'i' and 'I' and this is working
fine. Except for a possible [phishing
opportunity](https://www.theguardian.com/technology/2017/apr/19/phishing-url-trick-hackers). Why haven't the standard committees done the same for Turkish 'I' yet?
As for the [German letter
'ß'](https://en.wikipedia.org/wiki/%C3%9F), wikipedia says that
the uppercase variant 'ẞ' exists since 2008 (ISO 10646). Do
German people use it now?
```D
import std;
void main() {
"ß".asUpperCase.writeln; // prints "SS"
"ẞ".asLowerCase.writeln; // prints "ß"
"ẞ".asLowerCase.asUpperCase.writeln; // prints "SS"
}
```
