No, this is not a bug.
When dostring("print('\\b')") is parsed, the compiler sees a string
"print('\\b')", in which it then recognizes the escape sequence \\ and replaced
by the char \. So, the string is actually print('\b'). When this is parsed again
when dostring is executed, then \b is recognized as backspace, which is ascii 8.

To print \b (two-char string), you need to use
	dostring("print('\\\\b')")
