Chinese character width occupation problem about termbox-go HOT 3 OPEN

gbk is correct, utf-8 will have one more space in some environments

I found the problem. When dealing with wide characters, space adaptation should be added. Under gbk, chcp 936 is normal here, and under utf-8 chcp 65001, there is one more space, and the logic of deleting and adding spaces is fine。So don't switch cmd to utf-8. (maybe it's just my local problem)

// https://github.com/nsf/termbox-go/blob/master/api_windows.go
if runewidth.RuneWidth(rune(char.char)) > 1 {
    char.attr |= common_lvb_leading_byte
    chars = append(chars, char)
    // here 
    chars = append(chars, char_info{
	    char: char.char,
	    attr: char.attr | common_lvb_trailing_byte,
    })
}

bug description：It seems that wide characters do not need to add spaces under UTF-8 encoding? (I verified it locally, not sure if it is the case on other platforms or other machines)

how to solve

• GBK：There is no problem
• UTF-8：just Delete lines 130 to 134
  `https://github.com/nsf/termbox-go/blob/2ff630277754813b198ae96036e28e254d2c72bf/api_windows.go``
• ABOUT：Doing so may cause problems on mac or other platforms? No test, only for win platform

expected：Is it possible to judge whether the current chcp is equal to 65001 (UTF-8), and consider adding spaces? [I know that there may be many encoding formats that are inconvenient to adapt, just ask questions when encountering this situation]

I do not have this problem when using tbprint.

My editor can print Chinese or other UTF-8 characters as expected (without any spacing in-between)
