Hexdump shows the actual bytes in the file—the UTF-8 encoding of the runes (Unicode code points). Apparently you are reading them with utf8.DecodeRune or something like that; those return the code points, without the UTF-8 encoding. Andy -- You received this message because you are subscribed

[go-nuts] understanding utf-8 for a newbie

Hi. I decided to write a small program in Go to convert utf8 to simple ASCII. This need arose by my copying a file created in Ubuntu 16.04 amd64, and used on a win10 computer. I decided to first change ", ' and emdash characters. Using hexdump -C in Ubuntu, the runes in the file are:

A web framework that matches what you want to do will save you time. The trick is to spend less time evaluating frameworks than you save by using one. You could try mine. It's very simple, produces some useful basic stuff and doesn't force too many decisions onto you:

Hi, just a suggestion to improve go gen adoption rate, maybe. go generate is not included in the go build pipeline, for good reasons, especially for the core code. It s a two step command, 1- go gen 2- go build Although, since vendoring is implemented, I think it would be good to re think its

yeah i agree. But (:/), i think its pipeline issue in the consumption of a go package. In the same way the language is made to prevent user errors (as much as possible, and its difficult) that go get pipeline usage should help in that matter too. My point is not criticize, but the way you

For end users I strongly recommend distributing a binary. That gives you the ability to tag it properly and to know what goes into it - your code, your dependencies, and the compiler used. Typically this would happen by vendoring and using a Makefile or build script in the repo, running on some
