Dealing with Autodecode

[FilippoR via Digitalmars-d]

It's possible to add a new      alias bstring immutable(ubyte)[]

a new literal postfix (ustring s = "test string"b) or UFCS  
(ustring s = "test string".b)

add UFCS byCodePoint byGrapheme

and add overload function in phobos where necessary

so we can have a autodecode free string
