<pre>Currently, CodeBlockHash once converts the entire source code string to the UTF-8 string and pass it to SHA1 to calculate the hash value.
However, it's memory consuming because this process allocates a large buffer to store the entire UTF-8 string.
Instead of the current process (alloc, convert, and use), we should implement the streaming decoder decoding UTF-16 into UTF-8 and stream the bytes into SHA1 iteratively.</pre>
