Thanks Jonathan
I try to have a dynamic type
If sequence is immutable(char)[] AA become char[ubyte]
If sequence is immutable(dchar)[] AA become dchar[ushort] …
Then you can't put sequence in a range and get its value out
from there.
immutable(char)[]will be treated as a range of dchar, so you'll
get dchars,
not chars. If you want to operate on a string as chars, then
don't use it as a
range. The closest that you could get to operating on it as a
range of chars
would be to use std.string.representation and operate on it as
immutable(ubyte)[].

std.string.representation is great but return a numeric array
instead of numeric type. Ex ubyte[]
For ascii but me i try to get ubyte.
