The output of hexdump will be the actual bytes of the file; these are the UTF-8 encoded values. > However, when I write a simple program to display these runes from the file, > using the routines in unicode/utf8, I get very different values.

In Unicode lots of different things like letters, numbers, emoji, etc. are assigned numbers (Go's type for storing codepoints is called "rune"). These numbers are then encoded using an encoding such as UTF-8 to make the final output which you saw when you used hexdump. The Unicode codepoint of an em dash is always U+2014 (sometimes they're written this way, prefixed by `U+'), but the encoding might be different depending on what system you're on or what file format you're using. Here is an example of encoding a rune with the value 0x2014 as UTF-8, which gives the number you observed in your hexdump output: https://play.golang.org/p/ddIfzobKD4 —Sam -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
