I would probably go for std.utf.decode [1] to get the

concatenate the result with the rest of the string.

So by this I assume it is sufficient to work with dchars rather
than graphemes?
----------
import std.stdio;
import std.conv;
import std.string;
import std.uni;
size_t index = 1;
auto theString = "he\u0308llo, world";
auto theStringPart = theString[index .. $];
auto firstLetter = theStringPart.decodeGrapheme;
auto result = theString[0 .. index]
~ capitalize(firstLetter[].text)
~ theString[index + graphemeStride(theString, index) .. $];
writeln(result);

This will capitalize graphemes as a whole, and might be better
than what I previously wrote.
