How do I make these Perl regexs Python compatible?

I have these two lines in an old Perl script. When I write the Python equivalent I get all sorts of errors like valueerror: invalid \x escape, and stuff about encoding.

$line =~ s/[^\x{8}-\x{7B}]/ /ig;
$line =~ s/(Û|²|°|±|É|¹|Í)/ /g;

What do I need to do to get them working in Python?

For encoding issues, if you want to put Unicode characters in your source directly, you'll need to make sure the Python interpreter knows what your file encoding is. See:

I'm not too great with Perl regex but I think I may have solved it:

invalid_range = re.compile(r'[^\x08-\x7B]', re.I)
invalid_unicode = re.compile(ur'(Û|²|°|±|É|¹|Í)')
line = re.sub(invalid_range , '', line)
line = re.sub(invalid_unicode, '', line)
