charset error Golang 1.10.3 in custom GOPATH

[sandermirov]

I had an error while using package: charset: cannot open "charsets.json": open /usr/local/lib/go-charset/datafiles/charsets.json: no such file or directory GOPATH set to custom

Possible solution: From:

https://github.com/paulrosania/go-charset/blob/55c9d7a5834c4d034b34bf042103dbc646887f4f/charset/file.go#L24

to var CharsetDir = "/../datafiles"

And

https://github.com/paulrosania/go-charset/blob/55c9d7a5834c4d034b34bf042103dbc646887f4f/charset/file.go#L34

to

_, filename, _, _ := runtime.Caller(1)
r, err = os.Open(filepath.Join(path.Dir(filename)+CharsetDir, name))

@paulrosania Any news on this? Would you be open to a PR or do you recommend using another package instead of this one?

I don't think this repo is maintained anymore.

Seems like the approach now is to use golang.org/x/text/transform

[bombsimon]

Yep, transform seems to be it. I guess it depends on what exactly you're doing but I found some alternatives or wrapping APIs too. I reading CSV files and writing plan text so I've switch to the following alternatives.

Writing - golang.org/x/text/encoding/charmap

fileOnDisk, _ := os.Create(someFile)
latinWriter := charmap.ISO8859_1.NewEncoder().Writer(fileOnDisk)

if _, err := latinWriter.Write([]byte("latin1")); err != nil {
    return err
}

Reading - golang.org/x/net/html/charset

This method uses golang.org/x/text/transform for the reader and determine the encoding for you automatically.

fileOnDisk, _ := os.Open(someFile)
reader, err := charset.NewReader(fileOnDisk, "text/csv")
