'ç' is represented by 0xe7 in an encoding that is not UTF-8. :)

That would be a special agreement between the producer and the consumer 
of that string. Otherwise, 0xe7 is not 'ç'. I recommend ubyte[] for 
those cases.

In UTF-8, 0xe7 is the first byte of a 3-byte code point:

import std.stdio;

void main()
{
     char[] a = [ 'a', 'b', 'c', 0xe7, 0x80, 0x80 ];
     writeln(a);
}

Prints a Chinese character:

abc瀀
