Var B1,B2: TBytes; begin B1 := TEncoding.ANSI.GetBytes(myAnsiString); B2 := TEncoding.Convert(TEncoding.ANSI,

Question

Var B1,B2: TBytes; begin B1 := TEncoding.ANSI.GetBytes(myAnsiString); B2 := TEncoding.Convert(TEncoding.ANSI,

TEncoding.UTF8, B1);

why B1 = B2 ???

B1 = (199, 200, 230, 199, 225, 221, 214, 225)
B2 = (199, 200, 230, 199, 225, 221, 214, 225) 😩😩

Sorry, maybe you need to put special chars that does not have one of types(ansi or unicode) to be different.

let me make it simple: var ws : ansistring; B1,B2: TBytes; s: string; begin ws := 'Å'; ShowMessage(StringCodePage(ws).ToString); // = 1256 B1 := TEncoding.ANSI.GetBytes(ws); // = 63 B2 := TEncoding.Convert(TEncoding.ANSI, TEncoding.UTF8, s); // = 63 ss := TEncoding.UTF8.GetString(B2); // = ? show ? char 😐 you can test it

When you compare using "=" between objects is much different when you compare values of them. Pascal, Java, C and others languages you need to use methods to compare values of the object otherwise you compare if tobjects is the same. TBytes is an array of Byte then you need a method to compare using arrays.
