Question

Some UTF-8 characters like the UTF-8 equivalent of C2 96 (hyphen). On the browser it displays it as (utf box with 00 96). And not as \'-\'(hyphen). Any reasons for this be

Answer 1

The character you're talking about is an en-dash, not a hyphen. Its Unicode code point is U+2013, and its UTF-8 encoding is E2 80 93, not C2 96. That table you linked to is incorrect. The first two columns have nothing to do with UCS-2 or Unicode; they actually contain the windows-1252 encodings for the characters in question. The columns labeled "UTF-8 Hex" and "UTF-8 Native" are just plain wrong, at least for the rows labeled 128 to 159. The entities – and – represent an en-dash, but the UTF-8 sequence C2 96 represents a non-displayable control character.

You shouldn't need to encode those characters manually anyway. Just tell your text editor (or whatever you use to create the content) to save the file as UTF-8.
