[tyingq]

It would fail when you pass it 128. He's passing in values from 0-255. "Ascii" is sort of a misnomer in his post.

[jstimpfle → tyingq]

It's better to fail than to convert something that probably isn't latin1!

[mark-r → jstimpfle]

The latin1 codec doesn't fail for any values in the 0-255 range. It probably should, since there are values that don't map to a valid character. I don't know if this is deliberate and guaranteed or just an artifact of the current implementation. There should have been a 'byte' encoding that was explicitly made for 1:1 conversions.

[tyingq → jstimpfle]

Well, it's not clear what behavior he was looking for. And not possible to compare speed without an encoding that works for 0-255.
