Deserialize TArray<Byte> from an HTTPRequest.response

i receive an class from an http request
for example
test = class
fid = integer;
fhtmltext : tarray;

for the integer i use this term to deserialize := integer(TJSObject(Response.Result)['fid']);

is there a function to deserialize the tarray

and when i have the tarray data. how can i transform it to an string for the thtmldiv.html property?

or is this way to complicated and there is another way get get at least the string?

I'm not sure I understand your question.
You have a string encoded as an array of characters?
