[go-nuts] How to test for unicode property "Variation Selector"

I have some text that I'm processing which includes emoji. I'm trying to strip out all the emoji by using checking whether a rune fulfils unicode.IsSymbol(). This strips out the emoji, but it seems that some emoji include a unicode variation selector that is not stripped out. So I also need

[go-nuts] Should an input validation function correct the input?

In each of the handlers in an API I have, I first unmarshal the JSON request, and then validate the resulting struct. There are a few cases where I am able to pick up a correctable error in the validation code, but I'm not sure whether it's good practice to correct the error in the input data,

[go-nuts] Idiomatic way to reference custom error codes

[go-nuts] Converting escaped unicode to utf8

I have an application where I am processing a HTTP request with a JSON body. However, the JSON in the body has been unicode escaped, so instead of `wasn't`, I get `wasn\u0027t`. What is the simplest way to unescape this text back to utf8 encoded text. i.e. convert `wasn\u0027t` to `wasn't`.

[go-nuts] How to generate a positive int64 from byte slice

I have a byte slice 32 bytes long, and I would like to use it to generate a positive int64. Is there a standard way to do this, or do I need to write my own function (most likely using bit shifts)? The backstory is that I need to generate unique (low collision likelihood) integer IDs from emai
