er, it's important to note that though the ISO-8859-1 codepoints are the same as Unicode (below 256), the encodings are not the same (values above 127 are encoded multi-byte in utf-8, but values in ISO-8859-1 are always encoded single-byte).

I bet most people in this conversation know this, but it's a bit important to clarify. For me, it wasn't so long ago that I didn't know the difference between codepoint and encoding.
