in reply to Re^5: How to reverse a (Unicode) string
in thread How to reverse a (Unicode) string

In that case, we're back to the original question. Are there any encodings aren't "Unicode encodings"?

(Strictly speaking, the mapping isn't 1-to-1. U+2660 can't be encoded in iso-8859-1. You could also say that both U+00E9 and U+0065 U+0301 encode to E9 in iso-8859-1, although Encode's encode doesn't handle that.)
