Without RLE, I think you can get around this by positions not representing characters, but sequence starts.

But that is just implementation issue. Semantically, it is the same.

FYI, my new "String" implementation would go like this

class MString {
String text;
int character_count; // number of code units groups, e.g. graphemes
union {
byte *offsets; // for tiny strings
word *woffsets; // for small strings
dword *loffsets; // for really big strings
};

String operator[](int pos) { // not often used likely, more for demo
int pos1 = GetOffset(pos);
return text.Mid(pos1, GetOffset(pos + 1) - pos1);
}
}

The real challenge is to standardize these operations so you don't have to repeat them.

Yes. Hence MString. Note that with MString, after you perform Insert of another MString or Remove, you just update offset table, no need to iterate anything again.

PS: the high level stuff still is StringWalker territory.

Depends on what how you define "high level" Smile

Smile

For me, really high level abstraction is where you abstract from those little pesky issues and handle everything in high-level units (graphemes / characters).
