It is fine code. Why? Because if you assign s[42] you probably
know why you are do it and you most likely know that there is
a some ASCII character there.

Like for example

    s=get_some_utf8_text_code();
    
    for(size_t i=0;i<s.size();i++) {
        switch(s[i]) {
        case: '\r':
           case: '\n':
            case: '\t':
                s[i]=' ';
       }
     }

Something very common and useful for text parsing.
Is this code wrong? No!

If fast there is lots of code that works fine with this.
removing operator[] does not solve **any** problem.

Seems to me you hadn't seen Boost.Locale code and what does it
does.
