string is a simple array as well just with immutable(char) as elements. 
It is just an alias:

   alias string = immutable(char)[];

I understand how auto decoding can be bad but I doubt you need to 
process a char. char is a UTF-8 code unit, likely one of multiple bytes 
that represent a Unicode character; an information encoding byte, not 
the information. That code unit includes encoding bits that tell the 
decoder whether it is the first character or a continuation character. 
Not many programmer will ever need to write code to decode UTF-8.
