D's strings are Unicode.

Unicode has three main variants, UTF-8, UTF-16 and UTF-32.
The size of a code point is 1, 2 or 4 bytes.
But here is the thing, what is displayed (a character) could be multiple 
code points and these can be combined to form a grapheme.

So yes, there will be length mismatches between them :)
