gbk panic：character set not supported

[lsw45]

The OS‘s env:
#echo $LANG
zh_CN.gbk

And the code:

        t.keytimer = time.NewTimer(time.Millisecond * 50)
	t.charset = "UTF-8"

	t.charset = getCharset()
	if enc := GetEncoding(t.charset); enc != nil {
		t.encoder = enc.NewEncoder()
		t.decoder = enc.NewDecoder()
	} else {
		return ErrNoCharset
	}

@gdamore This is not my OS,I can't change LANG to UTF-8 or any other env. how to fix???

GBK is a legacy 16-bit encoding. Very surprising to see it -- would have expected GB18030 -- which is the newer Unicode compatible set.

I don't think the encoding library supports GBK at this time. However, there is a standard encoding/simplifiedchinese package that might be useful.

I don't really know anything about these encoding or character sets. I'll look to see if there is something easy I can do.

[gdamore]

Good news.

There is already a function called "RegisterEncoding" in tcell, and there is a GBK text encoding package.

So you can do:

import "golang.org/x/text/encoding/simplifiedchinese"

tcell.RegisterEncoding("GBK", simplifiedchinese.GBK)

You might also do so for GB18030 and HZGB2312 if you need to.

Also if you don't care about binary size, I have a pre-baked package you can just import:

import "tcell/v2/encoding"

This registers pretty much the entire set of reasonable ISO 8859, East Asian, and Cyrillic (KOI8) encodings.

[gdamore]

Oh, you have to do "encoding.Register()" to get them registered. :-)

[gdamore]

And if you pull from master, you'll get a change I just made which means all you have to do is import the tcell/v2/encoding package to get them all.
