> When encoding a String, there's a chance that there's a need to extend the size of the buffer if the String won't fit the buffer. However, when calculating whether extending is required, only the String size is counted without counting the num bytes counter at the start. As a result of that, a String might end up being truncated and lead to operation hanging up.
> This happened in executing a Script where the number of bytes sent as message ID was bigger than 27 and the script name being executed was exactly 23 characters.
