Converting string to byte[] creates zero character

Question

In this convert function

public static byte[] GetBytes(string str)
{
    byte[] bytes = new byte[str.Length * sizeof(char)];
    System.Buffer.BlockCopy(str.ToCh         


        

Answer 1

In reality .net (at least for 4.0) automatically changes size of char when serialized with BinaryWriter

UTF-8 chars have variable length (might not be 1 byte), ASCII chars have 1 byte

'ē' = 2 bytes

'e' = 1 byte

It must be kept in mind when using

BinaryReader.ReadChars(stream)

In case of word "ēvalds" = 7 bytes size will be different than "evalds" = 6 bytes
