safe access methods return '\0' for no char response.

  - indexOf
```
int indexOf(@NotNull
            @NotNull java.lang.CharSequence s)
```
    All index methods return the position or -1 if not found of the given character, characters or string.
    The basic methods have overloads for 1, 2, or 3 characters and CharSequence parameters. If fromIndex is not given then for forward searching methods 0 is taken as the value, for reverse searching methods length() is taken as the value
    For forward searching methods fromIndex is the minimum start position for search and endIndex is the maximum end position, if not given the length() of string is assumed.
    For reverse searching methods fromIndex is the maximum start position for search and startIndex is the minimum end position, if not given then 0 is assumed.
    
    Parameters:
    
    s - character pre whose occurrence to find
    
    Returns:
    
    index where found or -1
