Yes, that I tried, but the structure has a lot of lines of codes 
and so it is impractical and of course it will turn out difficult 
to debug.

Since this seems to be a dead-end I did reshuffle some things 
around:

```d
/// for illustration purposes only:
alias stringUTF08 = string;  /// = immutable(char )[];
alias stringUTF16 = dstring; /// = immutable(dchar)[];
alias stringUTF32 = wstring; /// = immutable(wchar)[];

alias stringUGC08 = gudtUGC!(stringUTF08);
alias stringUGC16 = gudtUGC!(stringUTF16);
alias stringUGC32 = gudtUGC!(stringUTF32);

public struct gudtUGC(typeStringUTF) {

    typeStringUTF whatever;

    ... lots of functions using typeStringUTF here

}

void main() {

    version (useUTF08) { stringUGC08 lugcSequence3 = 
stringUGC08(r"..."c); }
    version (useUTF16) { stringUGC16 lugcSequence3 = 
stringUGC16(r"..."d); }
    version (useUTF32) { stringUGC32 lugcSequence3 = 
stringUGC32(r"..."w); }

}

```

It works.

Thanks Ali :) !
