For compatibility with file encoding declarations, I believe this needs to be relaxed to starting with '#!python' in the source file encoding, rather than strictly b'#!python' (which will only be the case for ASCII compatible encodings).

I may be wrong, but I am not aware that Python is able to read encoding declarations in a non-ASCII compatible encoding :-)

Also, given the shebang line is for use by the OS, the appropriate encoding should be decided by the OS, not Python conventions. But I would surprised if a shebang-compatible used a non-ASCII encoding by default.

Antoine.
