Python's built-in functions ord and chr return UNICODE characters, which are based on 16-bit numbers, and numbers respectively. Is there a way to get extended ASCII characters (0-255), which are based on 8-bit unsigned numbers, without defining a dictionary to do so?

I can use Unicode characters, but its control characters are not as same as ASCII (specifically 10, 13, 26, and 255). These four numbers are the main reason I can't use Unicode because they are important to my code.

10: Line Feed

13: Carriage Return

26: Substitute

255: nbsp

Python3 has the bytes type, which has a decode method to convert each byte to the corresponding Unicode character. But since there are about a thousand difference byte-oriented character sets, you'll have to tell decode which one you're using.

The Python 3 default is 'utf-8', but the comment "255 is a control code" tells me that you're not using UTF-8. Neither I nor Python have a crystal ball, so you'll need to figure out the name of the character set you're using.

[edit] The "nbsp" probably means Non-Breaking Space, U 00A0. If that's encoded as 255, you're probably dealing with some flavor of DOS code page. .decode('cp850') may work, but as I said there are thousands of extensions, and guessing the wrong name will give weird Unicode output.
